I created a webpart for Moss 2007 using the MS Chart control. Everything works great but sometimes, when playing with the settings, the CPU of my server goes to 100% (w3wp.exe) and stays there. This is caused by chart control and not by the webpart code.
Offcourse i can do several checks to see if the required settings are ok but the control, should NOT take 100% from my CPU and should definitally not stay at 100%.
This behaviour takes place when i do not add a 'serie' or add a negative width and height and that sort of things.
I tried the same with the sample application MS provided. Setting the width or height of a chart to a negative value causes my server cpu to go to 100% and it stays there (10 min now). The chart API should give an exception in this case, but it doesn't.
I really do not want to deploy my webpart to our customers when there is the change of this happening.
Is it just my machine or does anybody else has the same experience? (i do not have another machine to try this out).
