Our current chart setup is as follows: 2 charts, each with 2 line series (~23k data points per line series – datetime [x-axis], double[y-axis]), data is added to the line series in real-time and all data is retained (never deleted). Both charts share a motion events group (pinchzoom, rollover, xaxisdrag, zoomextents).
If you zoom in to the furthest zoom possible, the chart/app starts to act extremely sluggish, then crashes eventually. – see attached txt file for logs.
Other solution suggestions are welcome.
That’s very strange. We have an example in our demo application which renders 3 lines series with few millions of points without any problems. Can you try to run it on same device that you’re using for testing?
Have you tried to memory profile your application? Based on your description it looks like that it could be caused by memory leak somewhere, but I can’t be sure without seeing the code. Can you provide a project that reproduces this issue so I can debug it?
