class TStyle: public TNamed, public TAttLine, public TAttFill, public TAttMarker, public TAttText

default constructor

 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

 Define the color model use by TPostScript and TPDF (RGB or CMYK).
 CMY and CMYK models are subtractive color models unlike RGB which is an
 additive. They are mainly used for printing purposes. CMY means Cyan Magenta
 Yellow to convert RGB to CMY it is enough to do: C=1-R, M=1-G and Y=1-B.
 CMYK has one more component K (black). The conversion from RGB to CMYK is:

 Double_t Black   = TMath::Min(TMath::Min(1-Red,1-Green),1-Blue);
 Double_t Cyan    = (1-Red-Black)/(1-Black);
 Double_t Magenta = (1-Green-Black)/(1-Black);
 Double_t Yellow  = (1-Blue-Black)/(1-Black);

 CMYK add the black component which allows to have a better quality for black
 printing. PostScript and PDF support the CMYK model.

 c = 0 means TPostScript and TPDF will use RGB color model (default)
 c = 1 means TPostScript and TPDF will use CMYK color model

 if the argument zero=kTRUE the minimum value for the Y axis of 1-d histograms
 is set to 0 if the minimum bin content is greater than 0 and TH1::SetMinimum
 has not been called.
 Otherwise the minimum is based on the minimum bin content.

 Set the number of divisions to draw an axis.
  ndiv      : Number of divisions.

       n = N1 + 100*N2 + 10000*N3
       N1=number of primary divisions.
       N2=number of secondary divisions.
       N3=number of 3rd divisions.
           e.g.:
           nndi=0 --> no tick marks.
           nndi=2 --> 2 divisions, one tick mark in the middle
                      of the axis.
 axis specifies which axis ("x","y","z"), default = "x"
 if axis="xyz" set all 3 axes

 Set color to draw the axis line and tick marks.
 axis specifies which axis ("x","y","z"), default = "x"
 if axis="xyz" set all 3 axes

 Set the size (in pixels) of the small lines drawn at the
 end of the error bars (TH1 or TGraphErrors).
 The default value is 2 pixels.
 Set np=0 to remove these lines

 Define a string to be inserted in the Postscript header
 The string in header will be added to the Postscript file
 immediatly following the %%Page line
 For example, this string may contain special Postscript instructions like
      200 200 translate
 the following header string will print the string "my annotation" at the
 bottom left corner of the page (outside the user area)
  "gsave 100 -100 t 0 r 0 0 m /Helvetica-Bold findfont 56 sf 0 0 m ( my annotation ) show gr"
 This information is used in TPostScript::Initialize

 Sets the fIsReading member to reading (default=kTRUE)
 fIsReading (used via gStyle->IsReading()) can be used in
 the functions myclass::UseCurrentStyle to read from the current style
 or write to the current style

 Define a string to be used in the %%Title of the Postscript files.
 If this string is not defined, ROOT will use the canvas title.

 Set axis labels color.
 axis specifies which axis ("x","y","z"), default = "x"
 if axis="xyz" set all 3 axes

 Set font number used to draw axis labels.
    font  : Text font code = 10*fontnumber + precision
             Font numbers must be between 1 and 14
             precision = 1 fast hardware fonts (steps in the size)
             precision = 2 scalable and rotatable hardware fonts
 The default font number is 62.
 axis specifies which axis ("x","y","z"), default = "x"
 if axis="xyz" set all 3 axes

 Set offset between axis and axis labels.
 The offset is expressed as a percent of the pad height.
 axis specifies which axis ("x","y","z"), default = "x"
 if axis="xyz" set all 3 axes

 Set size of axis labels. The size is expressed as a percent of the pad height.
 axis specifies which axis ("x","y","z"), default = "x"
 if axis="xyz" set all 3 axes

 Set line style string using the PostScript convention.
 A line is a suite of segments, each segment is described by the number of
 pixels. The initial and alternating elements (second, fourth, and so on)
 are the dashes, and the others spaces between dashes.

 Default fixed line styles are pre-defined as:

   linestyle 1  "[]"             solid
   linestyle 2  "[12 12]"        dashed
   linestyle 3  "[4 8]"          dotted
   linestyle 4  "[12 16 4 16]"   dash-dotted

  For example the following lines define the line style 5 to 9.

   gStyle->SetLineStyleString(5,"20 12 4 12");
   gStyle->SetLineStyleString(6,"20 12 4 12 4 12 4 12");
   gStyle->SetLineStyleString(7,"20 20");
   gStyle->SetLineStyleString(8,"20 12 4 12 4 12");
   gStyle->SetLineStyleString(9,"80 20");

 Note:
  - Up to 30 different styles may be defined.
  - The opening and closing brackets may be omitted
  - It is recommended to use 4 as the smallest segment length and multiple of
    4 for other lengths.
  - The line style 1 to 10 are predefined. 1 to 4 cannot be changed.

 set the default number of contour levels when drawing 2-d plots

 if optdate is non null, the current date/time will be printed in the canvas.
 The position of the date string can be controlled by:
  optdate = 10*format + mode
    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.
    format = 0 (default) date has the format like: "Wed Sep 25 17:10:35 2002"
    format = 1 date has the format like: "2002-09-25"
    format = 2 date has the format like: "2002-09-25 17:10:35"

  examples:
    optdate = 1  date like "Wed Sep 25 17:10:35 2002" in the bottom/left corner.
    optdate = 13 date like "2002-09-25" 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.

 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)
    p = 1;  print Probability
    c = 1;  print Chisquare/Number of degress of freedom
    e = 1;  print errors (if e=1, v must be 1)
    v = 1;  print name/values of parameters
  Example: gStyle->SetOptFit(1011);
           print fit probability, parameter names/values and errors.
    When "v"=1 is specified, only the non-fixed parameters are shown.
    When "v"=2 all parameters are shown.

  Note: gStyle->SetOptFit(1) means "default value", so it is equivalent to
        gStyle->SetOptFit(111)

 see also SetOptStat below.

 The type of information printed in the histogram statistics box
  can be selected via the parameter mode.
  The parameter mode can be = ksiourmen  (default = 000001111)
    k = 1;  kurtosis printed
    k = 2;  kurtosis and kurtosis error printed
    s = 1;  skewness printed
    s = 2;  skewness and skewness error printed
    i = 1;  integral of bins printed
    o = 1;  number of overflows printed
    u = 1;  number of underflows printed
    r = 1;  rms printed
    r = 2;  rms and rms error printed
    m = 1;  mean value printed
    m = 2;  mean and mean error values printed
    e = 1;  number of entries printed
    n = 1;  name of histogram is 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 !!
  WARNING: SetOptStat(1) is taken as SetOptStat(1111) (for back compatibility
           with older versions. If you want to print only the name of the histogram
           call SetOptStat(1000000001).
  NOTE that in case of 2-D histograms, when selecting just underflow (10000)
        or overflow (100000), the stats box will show all combinations
        of underflow/overflows and not just one single number!

  The parameter mode can be any combination of kKsSiourRmMen
    k :  kurtosis printed
    K :  kurtosis and kurtosis error printed
    s :  skewness printed
    S :  skewness and skewness error printed
    i :  integral of bins printed
    o :  number of overflows printed
    u :  number of underflows printed
    r :  rms printed
    R :  rms and rms error printed
    m :  mean value printed
    M :  mean value mean error values printed
    e :  number of entries printed
    n :  name of histogram is printed
  Example: gStyle->SetOptStat("ne");
           print only name of histogram and number of entries.
  gStyle->SetOptStat("n") print only the name of the histogram
  gStyle->SetOptStat("nemr") is the default

 Set paper size for PostScript output.

 Set paper size for PostScript output.
 The paper size is specified in centimeters. Default is 20x26.

 set the tick marks length for an axis.
 axis specifies which axis ("x","y","z"), default = "x"
 if axis="xyz" set all 3 axes

 if axis =="x"  set the X axis title color
 if axis =="y"  set the Y axis title color
 if axis =="z"  set the Z axis title color
 any other value of axis will set the pad title color

 if axis="xyz" set all 3 axes

 if axis =="x"  set the X axis title font
 if axis =="y"  set the Y axis title font
 if axis =="z"  set the Z axis title font
 any other value of axis will set the pad title font

 if axis="xyz" set all 3 axes

 Specify a parameter offset to control the distance between the axis
 and the axis title.
 offset = 1 means : use the default distance
 offset = 1.2 means: the distance will be 1.2*(default distance)
 offset = 0.8 means: the distance will be 0.8*(default distance)

 axis specifies which axis ("x","y","z"), default = "x"
 if axis="xyz" set all 3 axes

 any other value of axis will set the pad title size

 if axis="xyz" set all 3 axes

 see TColor::SetPalette

 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().

  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}
