Hi Joseph Griffin,
RadChart performance could suffer because of loading a lot of data (like 1000 data points or less but in lots of series), having a large resolution for the chart image, or using computation intensive appearance features such as blurred shadows or complex gradients. Another possible reason could be the usage of IntelligentLabelsEnabled
property (set to true)
. This has been designed to avoid label overlapping, but beyond certain number of items, the calculations for finding suitable position for each label might take a large amount of time.
Basically, the performance of the char depends to a large extent on the styles and configuration that you use, and on the performance of the app itself. That is why, I would recommend that after you build your application, simply test it to find out the maximum number of data points that allows the chart to perform as your client expects.
