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
