from Gabriel:
- deprecated GetCellContent / GetCellError / SetCellContent / SetCellError -> GetBinContent / GetBinError/ SetBinContent / SetBinError provide the same functionality ; replaced these methods across ROOT (still in graf2d and main)
- replaced SetCellError / SetCellContent / GetCellError / SetCellConten
- refactored redundant logic (GetContourLevel, SetContent, Interpolate, SetBufferSize)
- moved one-line methods to header file (SetMinimum, SetMaximum, GetXaxis, GetYaxis, GetZaxis, GetBinError)
- TH2::Rebin2D has been simplified (6 for loops -> 3 for loops) => 2-3x speedup

Fit parameters with very long name destroyed the stats display.
Example:
{
gStyle->SetOptFit(111);
TH1F *hist = new TH1F("hist","hist",100,-5,5);
TF1 *fit = new TF1("fit","gaus",-5,5);
fit->SetParName(2,"Parameter with very very very very long name");
hist->FillRandom("gaus",5000);
hist->Draw();
hist->Fit(fit);

Make sure the 2D drawing options COL, ARR, CONT and BOX are ignored when used to plot a 1D histogram. 1D histograms plotted with one of these options is now drawn with the default 1D plotting option. This is useful when the default option in the TBrowser is, for instance, COL. Before this change the 1D histogram appeared as blank as explained here https://savannah.cern.ch/bugs/index.php?95348.

Apply the patch suggested here:
https://savannah.cern.ch/bugs/?94807
With option COL TProfile2D histograms are handled differently because, for this type of 2D
histograms, it is possible to know if an empty bin has been filled or not. So even
if all the bins' contents are positive some empty bins might be painted. And vice versa,
if some bins have a negative content some empty bins might be not painted.

With option TEXT, do not draw the bins with 0 content for 1D
histograms to be consistent with the 2D histograms case.
Exemple:
root [0] TH1D * histo = new TH1D ("histo","",20,-5.,5.) ;
root [1] histo->FillRandom("gaus",1000) ;
root [2] histo->Draw("hist,text") ;

- Fix the bug submitted here: http://root.cern.ch/phpBB3/viewtopic.php?f=3&t=14257
In PaintTable the palette was deleted but not removed from the list of functions of the histograms. Later on the list of function was scanned (it was not empty). It crashed during the scan when the obsolete palette's null pointer was accessed. Now the palette is removed from the list of functions before being deleted. Similar wrong code was found in some other places (stats painting). The same fix has been applied (it was ok in PaintStats but wrong in PaintStats2 and PaintStats3).
- Remove some trailing blanks

- add support for asymmetric Poisson error in the histogram (when the histogram is not weighted)
- Add the methods TH1::GetBinErrorLow(ibin) and TH1::GetBinErrorUp(ibin)
- Add possibility to use different bin errors by using TH1::SetBinErrorOption(type). The type of errors which one can set are:
- TH1::kNormal</tt>: this are the default errors (symmetric) based on the normal approximation. Bin error = sqrt(N).
In case of a weighted histogram (non-integer bin content), the normal approximation is always used
- TH1::kPoisson: in this case the lower and upper error are defined by the 68% classical (frequentist) Poisson interval for N counts
(Garwood Poisson interval).
- TH1::kPoisson2: as above but in this case a 95% (2-sigma) Poisson interval is used.
- Add support in histpainter for drawing 1D and 2D asymmetric errors

When drawing scatter plot for TH2 or TH2Poly do not use gRandom, but an independent random generator instance,
to avoid interfering with gRandom
This fixes the bug <a href="https://savannah.cern.ch/bugs/?83021" >83021</a>.
Now the same sequence is also used for the same histograms, giving therefore the same scatter plot for the same
histogram.

From Olivier and me:
Split the TGraph classes to move the graphics code to separate classes.
These classes will be moved to the hist directory once the classes will be ok.
The TGraphs are painted via the TVirtualGraphPainter class and its concrete
implementation TGraphPainter.
At the difference of the TH1 classes for which a different painter is created
when drawing each histogram, one single TGraphPainter class is created.
The TGraphPainter class does not have internal state, all the information
from TGraph is passed to the drawing functions via parameters.

From Sergey Skononov:
This bug is connected with fixing bug #22317 which I submitted previously.
Unfortunately, I got it only after release 5.14 was published.
Due to the fix in THistPainter::PaintBarH the PaintAxis call was moved to the
very end of the routine. But, actually, it should come before the X and Y axis
pointers being permuted back. As I checked, now it looks like X axis
attributes have effect on the Y axis and vice versa.

Add new static function:
void THistPainter::PaintSpecialObjects(const TObject *obj, Option_t *option)
// Static function to paint special objects like vectors and matrices
// This function is called via gROOT->ProcessLine to paint these objects
// without having a direct dependency of the graphics or histogramming system

- Small fix to make sure the option "cont0" is always drawn with filled
contours (as said in the help). Without this fix the following lines
produced hollow contours:
root [0] gROOT->ForceStyle()
root [1] gStyle->SetFillStyle(1001)
root [2] gStyle->SetHistFillStyle(0)
root [3] hpxpy->Draw("cont0")

- PaintColorLevels: The modifications made in Revision 1.198 to
"take into account the option set by TStyle::SetHistMinimumZero"
is not appropriate for PaintColorLevels. It screws up completly the
correspondance between the color plot and the palette. The bad matching
was even worst with histogram having negative contents. Like in the
following example:
{
TH2F* histo = new TH2F( "histo", "histo", 3, 0.0, 3.0, 2, 0.0, 2.0 );
Int_t dummy;
dummy = histo->GetBin( 1, 1 );
histo->SetBinContent( dummy, -100.0 );
dummy = histo->GetBin( 2, 1 );
histo->SetBinContent( dummy, -90.0 );
dummy = histo->GetBin( 3, 1 );
histo->SetBinContent( dummy, 12.0 );
dummy = histo->GetBin( 1, 2 );
histo->SetBinContent( dummy, 45.0 );
dummy = histo->GetBin( 2, 2 );
histo->SetBinContent( dummy, 75.0 );
dummy = histo->GetBin( 3, 2 );
histo->SetBinContent( dummy, 100.0 );
gStyle->SetPalette( 1, 0 );
histo->Draw("colz");
histo->Draw("textsame");
}

-In TVirtualHistPainter.h replace the previous functions:
virtual void SetShowProjectionX() = 0;
virtual void SetShowProjectionY() = 0;
by one single function working for TH2 and TH3
virtual void SetShowProjection(const char *option) = 0;
-In THistPainter add the following functions:
virtual void SetShowProjection(const char *option);
virtual void ShowProjectionX(Int_t px, Int_t py);
virtual void ShowProjectionY(Int_t px, Int_t py);
virtual void ShowProjection3(Int_t px, Int_t py);
-In THistPainter.cxx implement the new function
void THistPainter::ShowProjection3(Int_t px, Int_t py)
// Show projection (specified by fShowProjection) of a TH3
// The drawing option for the projection is in fShowOption.
-In TH3, add the new function:
void TH3::SetShowProjection(const char *option)
// When the mouse is moved in a pad containing a 3-d view of this histogram
// a second canvas shows a projection type given as option.
// To stop the generation of the projections, delete the canvas
// containing the projection.
// option may contain a combination of the characters x,y,z,e
// option = "x" return the x projection into a TH1D histogram
// option = "y" return the y projection into a TH1D histogram
// option = "z" return the z projection into a TH1D histogram
// option = "xy" return the x versus y projection into a TH2D histogram
// option = "yx" return the y versus x projection into a TH2D histogram
// option = "xz" return the x versus z projection into a TH2D histogram
// option = "zx" return the z versus x projection into a TH2D histogram
// option = "yz" return the y versus z projection into a TH2D histogram
// option = "zy" return the z versus y projection into a TH2D histogram
// option can also include the drawing option for the projection, eg to draw
// the xy projection using the draw option "box" do
// myhist.SetShowProjection("xy box");
// This function is typically called from the context menu.
Note that this function is only partially implemented. It works only for the option "xy".
It is included in CVS as a framework for additional developments. see

- Since the axis for the CONT4 option are drawn using PaintAxis, it is
now possible to use gPad->RedrawAxis() on a 'cont4 plot' (It was not
possible before). This new possibility is now taken into account in
PaintAxis. The following macro illustrate the problem:
{
TH2F *h = new TH2F("h","test",40,-2,2,40,-2,2);
TRandom r;
for (Int_t i=0;i<10000;i++) {
h->Fill(r.Gaus(0,1),r.Gaus(0,0.6));
}
h->Draw("cont4");
c1->RedrawAxis();

- In case of 1D histograms plotted as a LEGO or a SURFACE, one had to change
the option LogZ to set the logarithmic scale on the Y axis. Setting the
option LogY produced an error. This is now fixed.
- More changes to be compliant with the coding conventions (comments format).

- PaintErrors:
In case of log scale on a Y axis with a positive maximum value and a minimum
value less or equal to 0, a new minimum is computed as a percentage of the
maximum. This rule is fine but may brings back visible some bins which are
out of range in linear mode. A new test has been added to prevent that. This
problem is visible since revision 1.197. Previously the test modified in that
revision was able to filter such wrong cases.

- PaintAxis:
The "long standing problem" mentioned in revisions 1.24 and 1.223 has been
identified. When an histogram is drawn with error-bars the values stored in
Hparam and those returned by gPad->GetUymin/max are different (because the
error-bars need more room to be drawn). The correct values are those returned
by gPad->GetUymin/max except in case of CONT4 (contours drawn with
TPainter3dAlgorithm) where Hparam must be used. The "long standing problem"
was visible with the following lines:
TH1D *h1 =new TH1D("h1","h1",100,-10,10);
h1->FillRandom("gaus");
h1->Draw("e");
gPad->RedrawAxis();
In that case the axis drawn by RedrawAxis are shifted compare to the original
ones.

- As indicated in the help of THistPainter::Paint, the option "A" used on
histograms means "do NOT DRAW the axis". This option worked properly on lego
and surfaces plots but not on 1D histograms and on "flat" 2D plots. Now it
is hopefully working in all cases.
A first attempt to make it work has been done in revision 1.226 of
THistPainter. But it was tagged as "catastrophic" in revision 1.228 because
it was not anymore possible to draw the TGraph axis.
Indeed, for historical reasons, the option "A" applied on TGraph means
exactly the opposite: "start a new plot and DRAW the axis".
So the needed modifications were a bit more complex than the ones done in
revision 1.226 of THistPainter. Actually some mods are needed in:
* THistPainter::PaintAxis: return if Hoption.Axis == -1 (option "A").
That was the "catastrophic" change of revision 1.226.
* THistPainter::PaintTable: Hoption.Axis<=0 replaces !Hoption.Axis.
* TGraph::PaintGraph: fHistogram->Paint(" ") replaces fHistogram->Paint("a").
* TPad::DrawFrame: hframe->Draw(" ") replaces hframe->Draw("a").

- Option "A" (to suppress the axis drawing on histogram plots) is now working
on 2D plots also. Hoption.Axis can have the following value:
Hoption.Axis = 0 ; User option = " " ; both axis and histogram are drawn.
Hoption.Axis = -1 ; User option = "A" ; axis are not drawn.
Hoption.Axis = 1 ; User option = "AXIS" ; only axis are drawn (not the grid).
Hoption.Axis = 2 ; User option = "AXIG" ; only the grid is drawn.
- Some clean up to make the rule checker happy.

- Since the axis are painted with PaintAxis() for the contour option CONT4
(in PaintContour), there is no need to have the funny values 0.0001 and
89.99 for the Phi and Theta angles (set with SetPhi() and SetTheta()). They
can be replaced by the exact value 0. and 90. This weird angles values were
needed when the axis were painted with TPaint3DAlgorithms. The exact values
produced wrong tick marks and labels placements.

- The contour option CONT4, is done by painting a colored surface seen
from top. With this technique the axis are painted by TPainter3dAlgorithms
as for normal lego or surface's axis. Therefore they did not behave like
the normal "2D axis" in particular:
* Tick marks were on the wrong axis' side.
* It was not possible to draw axis' grid.
* SetTickx() and SetTicky() had no effect.
This patch fixes this problems. The axis for CONT4 are now drawn with
THistPainter::PaintAxis(), not anymore using TPainter3dAlgorithms. To
achieve that, it was necessary to modify PaintAxis(): the axis label
(variables "umin" and "umax") are now computed from Hparam. This
modification is a partial "roll back" compare to revision 1.24. This
revision said:
"Correct THistPainter::PaintAxis to use axmin,axmax,aymin,aymax instead
of HParam.xmin, etc. This fixes a long standing problem when the
function TPad::RedrawAxis is called."
This comment is a bit useless because it doesn't tell what the "long
standing problem" was. Anyway, none of the known examples using
RedrawAxis didn't show a wrong behavior with the modified PaintAxis.
This is not surprising because "umin" and "umax" are the axis labels and
they do not act on the axis position.

From Olivier:
- The type of information printed in the histogram statistics box can be
selected via gStyle->SetOptStat(mode).
The parameter mode can be = iourmen (default = 0001111)
[...]
m = 1; mean value printed
m = 2; mean and mean error values printed
r = 1; rms printed
r = 2; rms and rms error printed
[...]
"m" and "r" can now be equal to 2, which mean "print the errors".

TH2D * base = new TH2D("base","base",10,-1,1,10,0.,1.5);

TH2D * h2d = new TH2D("h2d","h2d",10,0.,1.,10,0.,1.);
gStyle->SetPalette(1);
for (int i=0; i<10; i++) {
for (int j=0; j<10; j++) {
h2d->SetBinContent(i+1,j+1,(i+1)*10.+j+1);
}

(missing contour and FirstContour.C not working).

An algorithm sent by Ernst-Jan Buis for plotting contours using
the special projections for viewing skymaps or exposure maps has been
introduced in THistPainter and associated classes.
In Hoption.h a new member HOption.Proj has been introduced
int Proj; // = 1 to get an Aitoff projection, usefull for skymaps or exposure maps..
// = 2 to get a Mercator ptojection
// = 3 to get a Sinusoidal ptojection
// = 4 to get a Parabolic ptojection
in THistpainter::Paint, the following options are supported:
// "AITOFF" : Draw a contour via an AITOFF projection
// "MERCATOR" : Draw a contour via an Mercator projection
// "SINUSOIDAL" : Draw a contour via an Sinusoidal projection
// "PARABOLIC" : Draw a contour via an Parabolic projection
The function THistPainter::RecalculateRange has been modified to take into account these new options
as well as the class TPainter3dAlgorithms.
The picture produced by the new tutorial earth.C is visible at

Upgrade the histogram buffer algorithm such that it can be used in a
coming version of the rebinner of the TH1,2 editors.
When the histogram buffer is active (TH1::SetBuffer has been called),
the buffer is kept alive as long as the number of entries can
be accomodated by the buffer.
When calling the Draw/Paint functions, the histogram is reset and
refilled from the buffer.
The buffer is also preserved by the I/O operations.
The calling sequence of TH1::BufferEmpty has been modified to support
3 cases instead of 2.
Int_t TH1::BufferEmpty(Int_t action)
// action = -1 histogram is reset and refilled from the buffer (called by THistPainter::Paint)
// action = 0 histogram is filled from the buffer
// action = 1 histogram is filled and buffer is deleted
// The buffer is automatically deleted when the number of entries
// in the buffer is greater than the number of entries in the histogram

From Olivier:
- TH2::ProjectionX, TH2::ProjectionY, TH2::ProfileX and TH2::ProfileY can
now be performed according to graphical cuts.
Using a TCutG object, it is possible to select a sub-range of a 2-D histogram.
One must create a graphical cut (mouse or C++) and specify the name
of the cut between [] in the option.
For example, with a TCutG named "cutg", one can call:
myhist->ProjectionX(" ",firstybin,lastybin,"[cutg]");
To invert the cut, it is enough to put a "-" in front of its name:
myhist->ProjectionX(" ",firstybin,lastybin,"[-cutg]");
It is possible to apply several cuts:
myhist->ProjectionX(" ",firstybin,lastybin,[cutg1,cutg2]");
Example:
{
TCanvas *c = new TCanvas("c","example",0,0,700,600);
c->Divide(1,2);
TCutG *gcut = new TCutG("gcut",8);
gcut->SetPoint(0,-0.646552,0.932203);
gcut->SetPoint(1,-1.26437,0.105932);
gcut->SetPoint(2,-0.574713,-1.10169);
gcut->SetPoint(3,0.948276,-0.338983);
gcut->SetPoint(4,1.07759,0.720339);
gcut->SetPoint(5,-0.316092,-0.0847458);
gcut->SetPoint(6,-0.45977,0.402542);
gcut->SetPoint(7,-0.646552,0.932203);
TFile f("hsimple.root")
TH2F *hpxpy = (TH2F*)f.Get("hpxpy");
TH1D *hppx = hpxpy->ProjectionX("",1,40,"[gcut]");
c->cd(1);
hpxpy->SetFillColor(kBlue);
hpxpy->DrawCopy("box");
hpxpy->SetFillColor(kRed);
hpxpy->Draw("same box [gcut]");
c->cd(2);
hppx->Draw();
}

In THistPainter::DistancetoPrimitive when looping on list of associated functions
TF1::DistancetoPrimitive is called with -px instead of px to instruct
TF1::DistancetoPrimitive to not look in the histogram axis.
In case of a histogram with a negative minimum, do not select
the histogram when crossing the 0 line.

// The type of information about fit parameters printed in the histogram
// statistics box can be selected via gStyle->SetOptFit(mode).
// The parameter mode can be = pcev (default = 0111)
// v = 1; print name/values of parameters
// e = 1; print errors (if e=1, v must be 1)
// c = 1; print Chisquare/Number of degrees of freedom
// p = 1; print Probability
// When "v"=1 is specified, only the non-fixed parameters are shown.
// When "v"=2 all parameters are shown.
In THistPainter::PaintStat, take into account this option.
By default fixed parameters are not shown.

From Matt LeBourgeois:
fixes the problem with the drawing of empty bins. The fix was easy because
if there is a log scale then there can't be any negative values for z
therefore the logic statement was changed to if z==0 and
(zmin>0 or Hoption.logz) then continue.

In PaintContour, the patch done in the revision 1.167 was not correct. It
produced the following side effect: SetContour() called with a single
integer had no effect. This new version is similar to the logic we have in
other Paint functions using contours.

From Olivier:
TGraph2D is now split into 3 classes:
- TGraph2D (now in hist) to handle the basic graph 2d data
- TGraphDelaunay (in hist) to generate a Delaunay triangulation of a TGraph2D.
- TGraphPainter (in histpainter) to paint a TGraphDelaunay (used via
THistPainter)
- New function GetContourList in TGraph2D
- New option CONT5: draws a TGraph2D as a contour (using Delaunay
triangles).
- New TGraph2D constructor (from a TH2).
The class TSpectrum2 has been removed (still waiting for fixes from Miroslav)
NOTE: it is recommended to make distclean make
or at least
rm hist/src/G* graph/src/G*

Fix two problems reported by Andrei Gaponenko:
- must set bit kClipFrame in PaintContour. This is important when superimposing
several histograms with contours in the same pad and then zooming interactively
on the axes.
- When drawing in log scale a histogram with errors and the histogram has
a maximum close to 1 and a minimum of zero, the Y scale has been optimized.

This change is to make sure that the grid is drawn in the background

In cartesian or polar coordinates, option SURF3 is used.
* With option SURF4 (Gouraud shading) only the cartesian system was
allowed. This restriction (in the funtion analysing the plotting
options) has been removed because Gouraud shading works in all the
coordinate systems (POL, CYL, SPH and PSR).

Add a new entry Hoption.HighRes in Hoption_t. By default Hoption.HighRes =0.
It is non zero when the option "High Resolution 9 is selected in TH1::Draw.
The option low resolution is automatically selected in TGraph::PaintGrapHist
when the number of points is greater than the number of bins in the pad.
However, for some pathological cases (difficult to detect automatically)
like the example below, it is necessary to force high resolution.

Change THistPainter::PaintStat and PaintStat2 to implement the new logic
with TPaveStats. The "stats" object is now added to the list of functions
instead of being a member of THistPainter. With this change, it is easy
to support multiple stats box in the same pad.
//
// With the option "same", the statistic box is not redrawn.
// With the option "sames", the statistic box is drawn. If it hiddes
// the previous statistics box, you can change its position
// with these lines (if h is the pointer to the histogram):
//
// Root > TPaveStats *st = (TPaveStats*)h->GetListOfFunctions()->FindObject("stats")
// Root > st->SetX1NDC(newx1); //new x start position
// Root > st->SetX2NDC(newx2); //new x end position
It is not necessary anymore to change the name of the stats box if one wants
to add a new stats box. For example, the following works correctly:
hpx.draw();
hprof.Draw("sames"); //move teh position of teh stats box with the mouse
Note that the system is backward compatible is a user calls
TPaveStats *stats = (TPaveStats*)gpad->GetPrimitive("stats")
thanks to the new logic in TPad::GetPrimitive calling FindObject on each
object in the list.

Patch from Olivier
When drawing errors with option E3 it may happen that the number of points
in the final filled-area is smaller that 2*(the_number_of_error_bars).
In a such case the arrays used to draw the filled area must be arranged
before being plotted. The bug was visible with the following little macro:
void e3(){
TH1F* h_test = new TH1F("h_test","h_test", 45, 0, 12 );
for (Int_t i = 8; i <= 45; ++i) {
h_test->SetBinContent(i, 4.0);
Float_t error = (40.1-i)/40.0;
h_test->SetBinError(i, error);
}
TCanvas* canvas = new TCanvas("canvas", "canvas", 1);
h_test->SetMinimum(2);
h_test->SetFillColor(kRed);
h_test->Draw("E3");
h_test->Draw("E SAME");
}

From Olivier:
- Bug fixed in PaintPalette. Hparam.zmin and Hparam.zmax were used instead
of the real minimum and maximum of the histogram. This produced wrong
palette painting. The zmin and zmax in Hparam were used to handle Log
option on z axis. This is not necessary because if the maximum of the
histogram is <= 0 nothing is painted, and in the case where maximum is >0
and the minimum <= 0, TH1::GetMinimum returns a positive value equal to
max/1000.
- 2d functions painted with option COL produced empty boxes instead of
filled color boxes. This was a side effect of a change in the function
constructor in which the fill style is now set to "empty".
fH->SetFillStyle(1);
has been added in PaintColorLevels to fix that.
- In DefineColorLevels "theColor" should be computed as:
theColor = Int_t((i+0.99)....
to be compatible with the same value computed in PaintPalette
- A similar problem occurred in PaintContour. "theColor" was computed as:
Int_t((ipoly+1.99)... instead of: Int_t((ipoly+0.99) ...

eg scat=0.1, scat=3.14, scat=1e-5. Default is "scat=1".

improved TPaveStat layout by Olivier Couet.
- It handles properly the fit parameters.
- The vertical text positioning is better (uses the vertical alignment
"center").
- Chi2 is printed with the Greek characters.
I noticed that the right alignment of TLatex on screen is not always
perfect. On PS file it is perfect.

Use the new function TStyle::GetEndErrorSize to set the length of
the lines drawn at the end of the error bars.
// Use gStyle->SetErrorX(dx) to control the size of the error along x.
// set dx = 0 to suppress the error along x.
//
// Use gStyle->SetEndErrorSize(np) to control the size of the lines
// at the end of the error bars (when option 1 is used).
// By default np=1. (np reprersents the number of pixels).

Several optimisations in this patch:
- in PaintTitle, use TLatex::GetXsize to evaluate the length of the TPaveText
where to draw the title.
- In PaintContour, PaintLego, PaintPalette, simplify the logic computing the color
levels. The color palette is now coherent with the colors used in the
contour, including in case of user defined contours or a logZ scale.

New feature added by Philippe:
I am taking advantage of the fact that we have one painter per histogram
to individualize a little better the stats box.
The HistPainter now handles a pointer to the stats box. In particular this
means that you can rename it and still have it being updated. The stats can
also now be retrieved via hist->GetPainter()->GetStats(); The HistPainter
now keeps contact with the PaveStats box whether its name have changed or not.

Add new functionality to the histogram package via the new functions
SetBuffer, BufferFill and BufferEmpty.
virtual void SetBuffer(Int_t buffersize, Option_t *option="");
virtual Int_t BufferFill(Axis_t x, Stat_t w); //protected
virtual Int_t BufferEmpty();
Add new members:
Int_t fBufferSize; //fBuffer size
Double_t *fBuffer; //[fBufferSize] entry buffer
When SetBuffer is called, a dynamic buffer is created to hold up to
fBufferSize entries. When the standard Fill functions are called,
the arguments are put in the buffer, if a buffer is specified.
When the number of entries in the buffer is greater than fBufferSize,
the function BufferEmpty is automatically called.
BufferEmpty will fill the histogram with the entries in the buffer.
In case one of the axis has its lower limit greater or equal
to its upper limit, BufferEmpty calls the THLimitsFinder::FindGoodLimits
to compute the axis limits based on the entries in the current buffer.
When an histogram is created with an axis lower limit greater or equal
to its upper limit, the SetBuffer is automatically called with an
argument fBufferSize equal to fgBufferSize (default value=1000).
fgBufferSize may be reset via the static function TH1::SetDefaultBufferSize.

In THistPainter::PaintErrors, change the algorithm computing the length of the
line at the end of the error bars when option "e1p" is used.
The old algorithm computef the length as being proportional to the marker size.
The new algorithm, in addition, takes into account the "errorx" parameter
as given by gStyle->GetErrorx().

The THistPainter and TLego classes have been extended with
new functions to draw selected regions of a 2-d histogram.
One can create one or more graphical cuts (TCutG objects)
and specify this (these) cuts in option string of the Draw
function. Example, assuming two graphical cuts with name
"cut1" and "cut2", one can do:
h1.Draw("lego");
h2.Draw("[cut1,-cut2],surf,same");
The second Draw will superimpose on top of the first lego plot
a subset of h2 using the "surf" option with:
-all the bins inside cut1
-all the bins outside cut2
Up to 16 cuts may be specified in the cut string delimited by "[..]"
Currently only the following drawing options are sensitive to
the cuts option: col, box, scat, hist, lego, surf and cartesian
coordinates only.
A set of new functions has been added in THistPainter:
virtual Bool_t IsInside(Int_t x, Int_t y);
virtual Bool_t IsInside(Double_t x, Double_t y);
virtual Int_t MakeCuts(char *cutsopt);
The MakeCuts function is called by THistPainter::MakeChopt to fill
the new THistpainter data members: fNcuts, fCutsOpt and fCuts.
The functions IsInside are called by the THistpainter functions
or the TLego functions.

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.

- Optimize THistPainter::PaintErrors such that the vertical and horizontal
lines go to the marker without a gap.
- New options to draw contours for 2-d histograms.
The contour option "CONT" is now a pure 2-D option. It is not based
on the surface/lego algorithms.
This option computes now a set of points stored in a list of TGraph objects.
The points in the TGraph are sorted, such that one contour can be drawn
with one fill area. In addition, when the option "List" is specified,
the list of generated TGraph objects is stored in a TObjArray with the
name "contours". This TObjArray is accessible via gROOT->GetListOfSpecials().
When the option "CONT" is used, one can superimpose new contours on top
using the options "CONT1", "CONT2" or "CONT3".
The previous algorithm used by the option "CONT" is still available
as option "CONT4".
For example, the following call
h2->Draw("contzlist");
produces:
- a picture with surface colors to delimitate each contour
- the color palette.
- a list of the boundary points for each countour.
The points used to draw the contours are saved in the TGraph format
and are accessible in the following way:
TObjArray *contours =
gROOT->GetListOfSpecials()->FindObject("contours")
Int_t ncontours = contours->GetSize();
TList *list = (TList*)contours->At(i); //where i is a contour number
list contains a list of TGraph objects. For one given contour, more than
one disjoint polyline may be generated. The number of TGraphs per
countour is given by list->GetSize().
Here we show only the case to access the first graph in the list.
TGraph *gr1 = (TGraph*)list->First();

// 29 May
- Add the following note in the TPave, TPaveLabel and TPaveText constructors:
IMPORTANT NOTE:
Because TPave objects (and objects deriving from TPave) have their
master coordinate system in NDC, one cannot use the TBox functions
SetX1,SetY1,SetX2,SetY2 to change the corner coordinates. One should use
instead SetX1NDC, SetY1NDC, SetX2NDC, SetY2NDC.
28 May
- Modify THistPainter::PaintStat and PaintStat2 to use the TLatex character #pm
instead of +-
// 27 May
- Add new member functions:
Int_t TVirtualTreePlayer::GetDimension()
Int_t TTreePlayer::GetDimension()
GetDimension returns the number of dimensions in the TTree::Draw expression.
- Add new function in TTree;
void TTree::UnbinnedFit(const char *funcname ,const char *varexp, const char *selection="",Option_t *option=""
,Int_t nentries=1000000000, Int_t firstentry=0);
This function (origin Stephen Bailey) performs an unbinned fit to the
variable(s) given in varexp.
- Remove unused data member fDimension from class TTree.
- Introduce support for "Virtuality" in TLeafObject.
New data member fVirtual added and corresponding IsVirtual/SetVirtual functions.
By default, fVirtual is kTRUE.
This change allows new interesting possibilities in split mode. For example
if a member is TShape *fShape, a real object may be now of any type
derived from TShape (eg, TTUBE, TBRIK, etc).
With the previous version, the fShape object had to be of the declared
type TShape only.
When writing a TLeafObject, the class name of the object is now written in
the branch buffer by TLeafObject::FillBasket. When TLeafObject::ReadBasket
is called, an instance of the real class is built and its Streamer function
called.
This change is backward compatible. Old files can still be processed.
It is possible to set the virtuality for the branch to kFALSE via
TLeafObject::SetVirtual. Setting the virtuality to kFALSE makes
writing and reading faster and the file slightly smaller. In this case,
a TLeafObject must be of the type declared only.
- New minor changes in TGaxis (Damir Buskulic) for date/time format
in case the start time is not an integer value.
- Modify tutorial psexam.C to set the TPaveText TextFont to 61 instead of 62.
Font precision 1 bypass the TLatex logic.
- Mods in TLatex to remove the special treatment for characters ' and ".
Strings like l'#acute{e}toile are now correctly processed.
- Fix a bug in TGraph::GetFunction. (thanks Damon Spayde). The test
if (fFunctions) return 0; replaced by
if (!fFunctions) return 0;
