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

if (gROOT->GetClass("TStyleManager")) gSystem->Load("libGed");
void SetColorModelPS(Int_t c)
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
void SetHistMinimumZero(Bool_t zero)
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.
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"
if axis="xyz" set all 3 axes
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"
if axis="xyz" set all 3 axes
void SetEndErrorSize(Float_t np)
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
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
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
void SetIsReading(Bool_t reading)
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
void SetTitlePS(const char *pstitle)
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.
void SetLabelColor(Color_t color, Option_t *axis)
Set axis labels color.
axis specifies which axis ("x","y","z"), default = "x"
if axis="xyz" set all 3 axes
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"
if axis="xyz" set all 3 axes
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"
if axis="xyz" set all 3 axes
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"
if axis="xyz" set all 3 axes
void SetLineStyleString(Int_t i, const char *text)
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.
void SetNumberContours(Int_t number)
set the default number of contour levels when drawing 2-d plots
void SetOptDate(Int_t optdate)
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.
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.
When "v"=1 is specified, only the non-fixed parameters are shown.
When "v"=2 all parameters are shown.
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
m = 2; mean and mean error values printed
r = 1; rms printed
r = 2; rms and rms error printed
u = 1; number of underflows printed
o = 1; number of overflows printed
i = 1; integral of bins printed
s = 1; skewness printed
s = 2; skewness and skewness error printed
k = 1; kurtosis printed
k = 2; kurtosis and kurtosis error 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!

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"

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

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}
void SaveSource(const char *filename, Option_t *option)
Save the current style in a C++ macro file.
void SavePrimitive(ofstream &out, Option_t *)
Save a main frame widget as a C++ statement(s) on output stream out.
