Class Description

 TStyle objects may be created to define special styles.
 By default ROOT creates a default style that can be accessed via
 the gStyle pointer.

 This class includes functions to set the following object attributes.
   - Canvas
   - Pad
   - Histogram axis
   - Lines
   - Fill areas
   - Text
   - Markers
   - Functions
   - Histogram Statistics and Titles


TStyle() :TNamed()

TStyle(const char *name, const char *title) : TNamed(name,title)
 Create a new TStyle.
 The following names are reserved to create special styles
   -Default: the default style set in TStyle::Reset
   -Plain: a black&white oriented style
   -Bold:
   -Video;
   -Pub:
     (see the definition of these styles below).

 Note a side-effect of calling gStyle->SetFillColor(0). This is nearly
 equivalent of selecting the "Plain" style.

 Many graphics attributes may be set via the TStyle, see in particular
  - TStyle::SetNdivisions
  - TStyle::SetAxisColor
  - TStyle::SetHeaderPS
  - TStyle::SetTitlePS
  - TStyle::SetLabelColor
  - TStyle::SetLabelFont
  - TStyle::SetLabelOffset
  - TStyle::SetLabelSize
  - TStyle::SetOptDate
  - TStyle::SetLineStyleString
  - TStyle::SetOptFit
  - TStyle::SetOptStat
  - TStyle::SetPaperSize
  - TStyle::SetTickLength
  - TStyle::SetTitleOffset
  - TStyle::SetTitleSize
  - TStyle::SetPalette
  - TStyle::SetTimeOffset
  - TStyle::SetStripDecimals

  The current style is pointed by gStyle.
  When calling myStyle->cd(), gStyle is set to myStyle.
  One can also use gROOT to change the current style, eg
    gROOT->SetStyle("Plain") will change the current style gStyle to the "Plain" style
  See also TROOT::ForceStyle and TROOT::UseCurrentStyle

  a line is a suite of segments, each segment is described by the
  number of pixels. For example default line styles are defined as:
   linestyle 1  "[]"             solid
   linestyle 2  "[12 12]"        dashed
   linestyle 3  "[4 8]"          dotted
   linestyle 4  "[12 15 4 15]"   dash-dotted

  Up to 30 different styles may be defined.
   The opening and closing brackets may be omitted
   They will be automaticalled added by this function.

void SetOptDate(Int_t mode)
 if mode is non null, the current date/time will be printed in the canvas.
 The position of the date string can be controlled by:
    mode = 1 (default) date is printed in the bottom/left corner.
    mode = 2 date is printed in the bottom/right corner.
    mode = 3 date is printed in the top/right corner.
  The date position can also be controlled by:
    gStyle->SetDateX(x);  x in NDC
    gStyle->SetDateY(y);  y in NDC

  The date text attributes can be changed with:
    gStyle->GetAttDate()->SetTextFont(font=62);
    gStyle->GetAttDate()->SetTextSize(size=0.025);
    gStyle->GetAttDate()->SetTextAngle(angle=0);
    gStyle->GetAttDate()->SetTextAlign(align=11);
    gStyle->GetAttDate()->SetTextColor(color=1);

  The current date attributes can be obtained via:
    gStyle->GetAttDate()->GetTextxxxx();

  When the date option is active, a text object is created when the pad
  paint its list of primitives. The text object is named "DATE".
  The DATE attributes can also be edited interactively (position
  and attributes) via the normal context menu.

void SetOptFit(Int_t mode)
 The type of information about fit parameters printed in the histogram
 statistics box can be selected via the parameter 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 degress of freedom
    p = 1;  print Probability
  Example: gStyle->SetOptFit(1011);
           print fit probability, parameter names/values and errors.
 see also SetOptStat below.

void SetOptStat(Int_t mode)
 The type of information printed in the histogram statistics box
  can be selected via the parameter mode.
  The parameter mode can be = iourmen  (default = 0001111)
    n = 1;  name of histogram is printed
    e = 1;  number of entries printed
    m = 1;  mean value printed
    r = 1;  rms printed
    u = 1;  number of underflows printed
    o = 1;  number of overflows printed
    i = 1;  integral of bins printed
  Example: gStyle->SetOptStat(11);
           print only name of histogram and number of entries.
           gStyle->SetOptStat(1101);  displays the name of histogram, mean value and RMS.
  WARNING: never call SetOptStat(000111); but SetOptStat(1111), 0001111 will
          be taken as an octal number !!


void SetOptStat(Option_t *stat)
  The parameter mode can be = IOURMEN
    n ;  name of histogram is printed
    e ;  number of entries printed
    m ;  mean value printed
    r ;  rms printed
    u ;  number of underflows printed
    o ;  number of overflows printed
    i ;  integral of bins printed
  Example: gStyle->SetOptStat("ne");

Int_t CreateGradientColorTable(UInt_t Number, Double_t* Length, Double_t* Red, Double_t* Green, Double_t* Blue, UInt_t NColors)
 STATIC function.
 Linear gradient color table:
 Red, Green and Blue are several RGB colors with values from 0.0 .. 1.0.
 Their number is "Intervals".
 Length is the length of the color interval between the RGB-colors:
 Imaging the whole gradient goes from 0.0 for the first RGB color to 1.0
 for the last RGB color, then each "Length"-entry in between stands for
 the length of the intervall between the according RGB colors.

 This definition is similar to the povray-definition of gradient
 color tables.

 In order to create a color table do the following:
 Define the RGB Colors:
 > UInt_t Number = 5;
 > Double_t Red[5]   = { 0.00, 0.09, 0.18, 0.09, 0.00 };
 > Double_t Green[5] = { 0.01, 0.02, 0.39, 0.68, 0.97 };
 > Double_t Blue[5]  = { 0.17, 0.39, 0.62, 0.79, 0.97 };
 Define the length of the (color)-interval between this points
 > Double_t Stops[5] = { 0.00, 0.34, 0.61, 0.84, 1.00 };
 i.e. the color interval between Color 2 and Color 3 is
 0.79 - 0.62 => 17 % of the total palette area between these colors

  Original code by Andreas Zoglauer <zog@mpe.mpg.de>

void SetPalette(Int_t ncolors, Int_t *colors)
 The color palette is used by the histogram classes
  (see TH1::Draw options).
 For example TH1::Draw("col") draws a 2-D histogram with cells
 represented by a box filled with a color CI function of the cell content.
 if the cell content is N, the color CI used will be the color number
 in colors[N],etc. If the maximum cell content is > ncolors, all
 cell contents are scaled to ncolors.

 if ncolors <= 0 a default palette (see below) of 50 colors is defined.
     the colors defined in this palette are OK for coloring pads, labels

 if ncolors == 1 && colors == 0, then
     a Pretty Palette with a Spectrum Violet->Red is created.
   It is recommended to use this Pretty palette when drawing legos,
   surfaces or contours.

 if ncolors > 50 and colors=0, the DeepSea palette is used.
     (see TStyle::CreateGradientColorTable for more details)

 if ncolors > 0 and colors = 0, the default palette is used
 with a maximum of ncolors.

 The default palette defines:
   index 0->9   : grey colors from light to dark grey
   index 10->19 : "brown" colors
   index 20->29 : "blueish" colors
   index 30->39 : "redish" colors
   index 40->49 : basic colors

  The color numbers specified in the palette can be viewed by selecting
  the item "colors" in the "VIEW" menu of the canvas toolbar.
  The color parameters can be changed via TColor::SetRGB.

void SetTimeOffset(Double_t toffset)
 Change the time offset for time plotting.
 Times are expressed in seconds. The corresponding numbers usually have 9
 digits (or more if one takes into account fractions of seconds).
 Thus, since it is very inconvenient to plot very large numbers on a scale,
 one has to set an offset time that will be added to the axis begining,
 in order to plot times correctly and conveniently. A convenient way to
 set the time offset is to use TDatime::Convert().

void SetStripDecimals(Bool_t strip)
  Set option to strip decimals when drawing axis labels.
  By default, TGaxis::PaintAxis removes trailing 0s after a dot
  in the axis labels. Ex: {0,0.5,1,1.5,2,2.5, etc}
  If this function is called with strip=kFALSE, TGAxis::PaintAxis will
  draw labels with the same number of digits after the dot
  Ex: (0.0,0.5,1.0,1.5,2.0,2.5,etc}
