Dynamically building up chart

[User (Legacy)]

I have a VB form with 2 charts 

One is randomly generated scenarios, the other the results of a historgram 

based on the first. I would like to build these up dynamically, so the 

scenario lines get added to the top chart and the latest histograms gets 

plotted below until the desired number of charts has been reached. the only 

way i can get this to work is to use DoEvents, is there another faster 

method ? 

thanks
