I need a larger statics font size, but it does't work:
Reason for this problem:

* AUTHOR:
* ORGANIZATION: HEP group @ PKU
* COMPILER: gcc
*
* DESCRIPTION: ROOT couldn't automatically resize the width of statics box,
* so TStyle::SetStatFontSize() has no effect when the font's size is larger than
* the box. Therefore, you'd better reset new width by calling TStyle::SetStatW()
* whenever you call TStyle::SetStatFontSize(). Note: The height of the box can be
* resize automatically.

#include <TH1D.h>
#include <TCanvas.h>
#include <TStyle.h>
void SetStatFontSize()
{
TH1D* h = new TH1D("h","h title",100,0,10.);
h->Fill(1);
TCanvas* c = new TCanvas("c","",500,500);
gStyle->SetStatFontSize(0.14);
//To make sure SetStatFontSize() does work, you need next statement:
gStyle->SetStatW(0.7);
h->Draw();
}
New output with above codes:That's maybe a bug of TH class in ROOT.
