RE: gets(S) issue

So you see the 1st 10 correctly and then it goes wrong ? that's right ?

It is weird.. if it works for the 1st 10 it should be the same for the next 90 ones...

Can you send me the macro if does not require a huge environment to be run ?

Thanks Oliver,

getchar still gives plain Canvas,
but gets(S) allows me to see nearly 10 slices, after which the Canvas again becomes plain.

I have a while{} structure where I make and draw slices. Before this structure I created TCanvas (it isn't being created 100 times in while structure).

any ideas?

Dmitry

Put gPad->Update() before getchar. It should help.

Hi all,

I've got TH2F which i divide into slices, say 100 slices. Each slice I draw as a TH1F. I need to draw 1 slice, then look at it , press anykey and see another on the same TCanvas. Instead ROOT just produceds 100 of them quickly, so the only one i can see is the 100th slice (last one).

I tried getchar and gets functions, they work, but Canvas remains plain white all the time.

Is there any way to manually renew the Canvas, or probably some other key-awaiting functions.

Thanks a lot,
Dmitry
