SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components

I have written my first SciChart WPF application using the latest free trial version (4.0.5.8246). It is a simple evaluation application that draws one or more lines with each line defined to have 100 or more points. I am using the following SciChart types from the n4.5 DLLs:

SciChartSurface
NumericAxis
FastLineRenderableSeries
XyDataSeries<double,double>

Also, I have my project platform target set to x64 and Debug. I have verified I have DirectX installed (SDK, June 2010, 9.29.1962.0).

How can I be sure that DirectX is being used for rendering and not software rendering?

I have attached the code for this fairly simple application.

Thanks,
Dave

Hi Dave,

Thanks for writing to us. Have you seen our Performance tips & tricks article? You can find there some basic things which can have a great impact on performance. Please ensure you are following the suggestions from this article.

Concerning the DirectX rendering plugin, please take a look at this article – DirectX vs. Software comparison. It shows how much faster SciChart is with DirectX enabled.

Finally, with SciChart WPF v6 or greater, you can enable the new Visual Xccelerator Engine for up to 100x faster charts.

Hope this helps! Please let us know if there are still any performance issues,

Thanks for your reply, which did provide the information I needed to use the DirectX rendering surface. I now get better performance with my evaluation application.

Thanks,
Dave
