we're using syncfusion essential charts for winforms in ver.

I'd like to ask. what's the difference between
1. adding point into memory model (IChartSeriesModel) and then throwing Changed event and
2. adding same point without throwing event and calling Redraw on ChartControl instead?
What are the considerations (mainly to performance) when using Redraw method and what's exactly difference between argument false and true?

thanks in advance for your help!

Hi Lubos,

There is no difference. Syncfusion chart draws complete chart even if you add only one ChartPoint. It does not clip the region and draw only the newly added points. Hopefully it will be improved in the future.
