  If I add 60k datapoints to a FlexChart, it starts to lag.
  
  For example when I resize the panel, or use the zoom / pan features.
  
  Zoom, in particular, seems to keep zooming after I release the mouse wheel.

  If I only add 10 point to the chart, everything is much smoother / snappier.

  Is there a way to get better performance with 60k points and above?

  I need a Line chart with maybe 10-20 series with 60k points each.

  Hi Lars,

  Since you are using a very large number of datapoints in your flexchart, there could be a performance issue using while rendering. However, in order to exactly replicate the issue, we request you let us know how exactly you are loading your datapoints on your flexchart.

  Please share with us the data points that you are using. Additionally, provide a stripped-down version of your sample application that shows the issue. This will help us investigate the issue in a better way.

  Thanks & Regards,
