    I'm having performance issues with my RadCartesianChart. I'm trying to plot an average of 10000 points (but would like to go as far as 40000). Is this simply too many points for the chart to handle fluently?

    Are there any generaltips anyone can give to speed up a RadCartesianChart? Any property settings that are known to slow it down?

    Kind regards,

    Hello Jeroen,

    Could you elaborate a bit on your specific project requirements and what would you expect from the chart control - desired chart type, desired interactivity settings, is pan/zoom required / enabled, is this a live data scenario, how does your data look like, etc.?

    Generally the default configuration of the control is pretty lightweight and there are no properties enabled by default that you can toggle to speed it up but usually when visualizing such a large amount of data, we are using the built-in data sampling functionality provided as part of the external ChartDataSource control (we have attached a runnable sample application that demonstrates this approach).
