Drawing a Canvas

Hi rooters, I'm new to the family and what I would very carefully 
describe as unexperienced. I have the following problem:


Inside a macro I create a Canvas with all bells and whistles  

I create two pads and with them a histogram each               

I "Draw" the pads and histograms and here the problems start: 

I get the canvas with the histograms, but the menu line never gets 
finished or even started. The canvas can be varied in size but the 
histograms are never adapted. 

I do some other stuff in a loop that later is supposed to fill the 
histograms but currently leaves them untouched and empty. After each loop 
I call the Update method on the Canvas. Nothing happens...

After this" other stuff" is done the histograms are saved and the file 
is closed: That works again. The same thing can be done over and over again.
The only problem is the "nonfinished drawing"...

What do I do wrong?

Thanks,

Tassilo
