  Hello,

  we display a lot of data points in the FlexChart Line. In order to show only part of the data we used the Scroll function or Range Selector function, but in both cases there was a clear slowdown as soon as we loaded a database with more than 2000 values.

  Maybe there is another way to handle with huge data?

  How much data can FlexChart containт (Data Points and Series)?

  Hi Ganna,

  There is no limit for the number of Series/DataPoint that can be used with FlexChart. However, using a large amount of data/series can cause performance issues depending on the chart type used and resources available on the system.

  You can try setting FlexChart’s RenderMode property to DirectX to improve performance as follows:

  
  flexChart.RenderMode = RenderMode.DirectX;
  
  

  Just in case if you still face this issue then I would request you to share a stripped-down sample replicating this behavior.

  Best Regards,
