		Hi,

	I have some problem to update canvas, I've tried the following
commands :

TFile f("myfile.root");
TTree *myt = Mytree;
TCanvas *myc = new TCanvas("myc","myc_titre",0,0,400,600);

myc->Divide(1,2);
myc_1->cd();
myt->Draw("var1");
myc->cd(2);
myt->Draw("var2");

Here everything works fine ... then

myc->Divide(2,2);
myc->cd(1);
myt->Draw("var3");
myc->cd(2);
myt->Draw("var4");     
...

Here my canvas is never updated ... I've tried myc->Update(); and
myc->Modified(); in different places but it does not change the result.

Do I have to create again a new canvas before the second Divide ? Is there
something wrong in the few lines above ?

			Thanks,

				Sabine.

PS. Is there an equivalent to the "wait" we can use in PAW macros between
the drawing of 2 histos ?
