the gStyle pointer.
This class includes functions to set the following object attributes.

See SetLineStyleString for more explanations
void GetPaperSize(Float_t &xsize, Float_t &ysize)
Set paper size for PostScript output
Float_t GetTickLength( Option_t *axis)
Float_t GetTitleOffset( Option_t *axis)
Float_t GetTitleSize( Option_t *axis)
void SetNdivisions(Int_t n, Option_t *axis)
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"
void SetAxisColor(Color_t color, Option_t *axis)
Set color to draw the axis line and tick marks.
axis specifies which axis ("x","y","z"), default = "x"
void SetHeaderPS(const char *header)
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
This information is used in TPostScript::Initialize
void SetLabelColor(Color_t color, Option_t *axis)
Set axis labels color.
axis specifies which axis ("x","y","z"), default = "x"
void SetLabelFont(Style_t font, Option_t *axis)
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"
void SetLabelOffset(Float_t offset, Option_t *axis)
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"
void SetLabelSize(Float_t size, Option_t *axis)
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"
void SetLineStyleString(Int_t i, const char *text)
Set line style string (used by Postscript)
PostScript uses the following convention
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 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.
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 = ourmeni (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.
void SetPaperSize(EPaperSize size)
Set paper size for PostScript output.
void SetPaperSize(Float_t xsize, Float_t ysize)
Set paper size for PostScript output.
The paper size is specified in centimeters. Default is 20x26.
void SetTickLength(Float_t length, Option_t *axis)
set the tick marks length for an axis.
axis specifies which axis ("x","y","z"), default = "x"
void SetTitleOffset(Float_t offset, Option_t *axis)
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"
void SetTitleSize(Float_t size, Option_t *axis)
Set the axis title size.
axis specifies which axis ("x","y","z"), default = "x"
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 > 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.
