Hi,

I am using Nevron chart version 12.2.6.12 for .NET 2011 Volume 1.

I am experiencing performance issues when loading large data sets. Eg. Three graphs with one line in each. Each line has 200000 points or more. The chart becomes unresponsive and reacts with great delay.

Any ideas on how to improve performance?

Best regards
Kasper

Hi Kasper,
In newer versions of the control you have the option to enable line sampling:
line.SamplingMode = SeriesSamplingMode.Enabled;
and / or to enable hardware accelerated rendering:
nChartControl1.Settings.RenderSurface = RenderSurface.Window;
So you may consider to upgrade. We would recommend you to test whether newer versions of control can meet your performance requirements (the control works with 1M+ data points without a problem). If it covers your requirements please contact sales@nevron.com for pricing / special promotions / discounts etc.
Hope this helps - let us know if you have any questions or meet any problems.

Best Regards,
Nevron Support Team
