The histogram statistics painter class.

To draw histogram statistics and fit parameters.

Statistics Display

The type of information shown in the histogram statistics box can be selected with:

gStyle->SetOptStat(mode);

mode

Option_t Option_t TPoint TPoint const char mode

Definition TGWin32VirtualXProxy.cxx:68

gStyle

R__EXTERN TStyle * gStyle

Definition TStyle.h:436

TStyle::SetOptStat

void SetOptStat(Int_t stat=1)

The type of information printed in the histogram statistics box can be selected via the parameter mod...

Definition TStyle.cxx:1640

The "`mode`" has up to nine digits that can be set to on (1 or 2), off (0).

mode = 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

For example:

gStyle->SetOptStat(11);

displays only the name of histogram and the number of entries, whereas:

gStyle->SetOptStat(1101);

displays the name of histogram, mean value and RMS.

WARNING 1: never do:

gStyle->SetOptStat(0001111);

but instead do:

gStyle->SetOptStat(1111);

because 0001111 will be taken as an octal number!

WARNING 2: for backward compatibility with older versions

gStyle->SetOptStat(1);

is taken as:

gStyle->SetOptStat(1111)

To print only the name of the histogram do:

gStyle->SetOptStat(1000000001);

NOTE that in case of 2D histograms, when selecting only underflow (10000) or overflow (100000), the statistics box will show all combinations of underflow/overflows and not just one single number.

The parameter mode can be any combination of the letters 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

For example, to print only name of histogram and number of entries do:

gStyle->SetOptStat("ne");

To print only the name of the histogram do:

gStyle->SetOptStat("n");

The default value is:

gStyle->SetOptStat("nemr");

When a histogram is painted, a TPaveStats object is created and added to the list of functions of the histogram. If a TPaveStats object already exists in the histogram list of functions, the existing object is just updated with the current histogram parameters.

Once a histogram is painted, the statistics box can be accessed using h->FindObject("stats"). In the command line it is enough to do:

Root > h->Draw()

Root > TPaveStats *st = (TPaveStats*)h->FindObject("stats")

h

#define h(i)

Definition RSha256.hxx:106

TObject::FindObject

virtual TObject * FindObject(const char *name) const

Must be redefined in derived classes.

Definition TObject.cxx:408

TPaveStats

The histogram statistics painter class.

Definition TPaveStats.h:18

because after h->Draw() the histogram is automatically painted. But in a script file the painting should be forced using gPad->Update() in order to make sure the statistics box is created:

h->Draw();
gPad->Update();
TPaveStats *st = (TPaveStats*)h->FindObject("stats");

Without gPad->Update() the line h->FindObject("stats") returns a null pointer.

When a histogram is drawn with the option "`SAME`", the statistics box is not drawn. To force the statistics box drawing with the option "`SAME`", the option "`SAMES`" must be used. If the new statistics box hides the previous statistics box, one can change its position with these lines ("`h`" being the pointer to the histogram):

Root > TPaveStats *st = (TPaveStats*)h->FindObject("stats")
Root > st->SetX1NDC(newx1); //new x start position
Root > st->SetX2NDC(newx2); //new x end position

To remove the border or shadow of the TPaveStats, use the function TPave::SetBorderSize

To change the type of information for an histogram with an existing TPaveStats one should do:

st->SetOptStat(mode);

TPaveStats::SetOptStat

void SetOptStat(Int_t stat=1)

Set the stat option.

Definition TPaveStats.cxx:308

Where "`mode`" has the same meaning than when calling gStyle->SetOptStat(mode) (see above).

One can delete the statistics box for a histogram TH1* h with:

h->SetStats(0)

and activate it again with:

h->SetStats(1).

Fit Statistics

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 degrees of freedom
e = 1;  print errors (if e=1, v must be 1)
v = 1;  print name/values of parameters

Example:

gStyle->SetOptFit(1011);

TStyle::SetOptFit

void SetOptFit(Int_t fit=1)

The type of information about fit parameters printed in the histogram statistics box can be selected ...

Definition TStyle.cxx:1593

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)

Statistics box editing

The following example show how to remove and add a line in a statistics box.

 
TCanvas *statsEditing() {
   // Create and plot a test histogram with stats
   TCanvas *se = new TCanvas;
   TH1F *h = new TH1F("h","test",100,-3,3);
   h->FillRandom("gaus",3000);
   gStyle->SetOptStat();
   h->Draw();
   se->Update();
 
   // Retrieve the stat box
   TPaveStats *ps = (TPaveStats*)se->GetPrimitive("stats");
   ps->SetName("mystats");
   TList *listOfLines = ps->GetListOfLines();
 
   // Remove the RMS line
   TText *tconst = ps->GetLineWith("RMS");
   listOfLines->Remove(tconst);
 
   // Add a new line in the stat box.
   // Note that "=" is a control character
   TLatex *myt = new TLatex(0,0,"Test = 10");
   myt ->SetTextFont(42);
   myt ->SetTextSize(0.04);
   myt ->SetTextColor(kRed);
   listOfLines->Add(myt);
 
   // the following line is needed to avoid that the automatic redrawing of stats
   h->SetStats(0);
 
   se->Modified();
   return se;
}
