I have a situation where I need to have a lot of independent realtime charts rendered on the screen at the same time. I have put a scichart into a user control and that user control into a list so I can reuse my configuration.
Unfortunately, the behavior I am seeing is that when I have more than 5 charts, the charts stutter really badly. I’m using the SciChartPerformanceOverlay to determine what the FPS is of each of the charts.
I can see that in my 5 chart situation, if my mouse cursor is NOT over the window or NOT moving on the window, each chart has an FPS of ~18 for SciChartSurface and an FPS of >500 for Composition Target. When I start to move the mouse around on top of the window, the SciChartSurface FPS value drops to < 5 and the Composition Target drops to ~300.
I’ve got no mouse events hooked up, I’ve set TryApplyDirectXRenderer to true and it seems to accept it. I’ve double-checked the following values:
I’m suspending the chart before adding points. Each chart only has 1000 points inside a XyDataSeries<int, double> that is databound to a FastLineRenderableSeries. I’m even using Update instead of Append to try to reuse the same memory, in case that makes a difference.
I’ve played with the MaxFrameRate and nothing seems to help.
My dev machine is a bit old and the graphics card is Intel-based, but I never imagined the performance would get so bad so quickly. I’m hoping there’s something I’m missing here as I’ve read such good things about SciChart.
Please let me know if there’s any advice.
