Non-responsive when changing Stacked Style


Recommended Posts

Hi, I have an application which dynamically changes the stacking style for a 3D chart. It would appear that the values I am passing to the chart cause it run very slowly and sometimes use up all available memory. This behaviour only appears to occur for some combination of stacking styles with 3D views. I have included a small sample project with demonstrates the issue when you click the Update button. If you remove the "/ 100000" in the property setters, the program will run very slowly or become non-responsive. The smaller the value you use (say 1,000; 100; 100) the slower it runs. I am using Visual Studio 2010 on a Windows 7 machine. Please let me know if you require more information. Jonathan

Starting in build 3958 (available as a hotfix here) we have fixed a couple of issues related to changing axis properties while the chart is 3D. In this case changing the stacked style requires an axis recalculation as the max will change.

We are still researching if the fix takes care of all the issues but wanted to make it available as soon as possible in case this was stopping you.

Please remember that if UAC is enabled in your machine you must make sure you run IE as an Administrator to apply the update.
