Hello Rooters!
TPad::DrawFrame is used to force
an empty frame with the x and y axis drawn
(similar Null command in Paw).
In many cases I'd like to call it several times for
the same pad but calling
gPad->DrawFrame(xmin,ymin,xmax,ymax,title) several times
cause memory leakage because each time new TH1F is created
TH1F *hframe = new TH1F("hframe",title,100,xmin,xmax);
I think it would be better correct this by testing
if (!GetListOfPrimitives()->FindObject("hframe"))
TH1F *hframe = new TH1F("hframe",title,100,xmin,xmax);
With best regards , Valery
