    We are implementing a charting control in our application where we need to be able to show large datasets.

    While testing we seem to hit a performance limit with 10k+ datapoints, after which the chartview starts getting unresponsive to the point it becomes unusable. We are databinding the chartview to a array of point values.

    I am unable to locate examples with large datasets, and I would very much appreciate a hint to how this can be achieved.

    What we need is to be able to work with up to 500 000 datapoints.

    Hello Anders,

    In such scenarios we would suggest you to consider using the built-in data sampling functionality provided in the form of an external ChartDataSource control -- you can find more information here.

    Hope this helps.
