Dear Rooters,
I would like to change some parameters of the global styles, e.g. changing
the font to Roman on histogram labels, axis, legends etc. I know how to
this for each object (h->GetXaxis()->SetTitleFont(22)), but I want to do
this once at the beginning of a macro and not separately for each object.
Therefore I created a style like in the attached macro.
But I encounter several problems:
- the font for the Yaxis is not changed
- how to change the font for the legend in the style definition?
- as described in the manual, the new style must be called before reading
objects from a file. Then how can I make in one macro two plots from the
same histogram (read from a file), first with MyStyle1 and then with
MyStyle2? The obvious way would be something like this (assume there is a
canvas divided into two pads):
c1_1->cd()
gROOT->SetStyle(MyStyle1);
hist->Draw();
c1_2->cd();
gROOT->SetStyle(MyStyle2);
hist->Draw();
But as I understand from the manual this won't work.
I am using the HEAD version of root on RedHat7.2.1.
Thanks,
Jochen
{
gROOT->Reset();
TStyle *Sty = new TStyle("MyStyle","My Style");
Sty->SetTitleFont(22);
Sty->SetLabelFont(22);
Sty->SetOptStat(0);
gROOT->SetStyle("MyStyle");
TH1F *h = new TH1F("h","A Gaussian distribution",20,-3,3);
h->FillRandom("gaus",1000);
h->GetXaxis()->SetTitle("X-Title");
h->GetYaxis()->SetTitle("Y-Title");
h->Draw();
TLegend *leg = new TLegend(0.6,0.7,0.85,0.8);
leg->AddEntry(h,"A Gaussian distribution");
leg->Draw();
}
