Ok, I see your point, but sometimes it's just easier to do it than to go some other way. In my case I use a java library called highcharts on letstrend.com. This creates the graphs for my stocks on the aspx page. But before I can create the graphs I have to grab the data from Yahoo, then process it, format it so that I can use the highcharts library. All that is done in real time and in the background. There's no way to do it in the aspx file.
