As far as i can see, the chart always renders and scales the chart area after each DataPoint addition.
1. Can i determine a fixed scale for my axes ?
2. Can i control the chart drawing rate (i do not need the animation) ?
3. Do you have performance issues ?

Hi nir,

Onto your questions:
  1. You can set a fixed scale for Y axis by setting AutoScale property to false and providing values for MinValue, MaxValue and Step property. Unfortunately, the X axis can only be auto-scaled for the moment
  2. You can disable animations with a single line of code: RadChart1.DefaultView.ChartArea.EnableAnimations = false;
  3. We have performed some optimizations in the chart for the upcoming service pack release, but still any statement here could be argued. A performance one considers unacceptable could be really fine for another. I would suggest that you modify any of our examples, so that the chart displays as many items as you need and evaluate the performance.

Hello nir,

We have planned this for Q3 later this year. We will do our best to include it in an earlier release, but we cannot be certain about it.
