the questions is listed like below
1 After doing the following example the chart crashed.
for (int i = 0; i < 2; i++)
{
ChartArea.DataSeries.First().Add(new DataPoint(i, 8E-308));
}
2 When five hundred or more DataPoints are added to the chart the refresh rate of the chart is so slow that it always makes me think the chart crashes.
Do you have any solutions?Thanks!

Thank you!
While I was not able to reproduce the crash with very small values (like 8E-308), the chart indeed did not display its Y axis correctly, so I have forwarded this issue to our developers. I have also updated your Telerik points. As for the performance issue - even with a thousand items on my end the chart appears within a second. You may need to disable animations with so many items. Also, please make sure you use the latest version of the control.

I have ask the same question sometime ago.The following is the ask and answer.
Hello,
I have a question, if I don't set the property of axisY, the default value of AutoRange is 'true' .
Like following example, First I add some plus value to the dataseries , and then I add some minus value to the dataseries.
After that the chart crashes, it just can't show the points I add.
Can you help me to solve the problem? Thank you!
for (int i = 0; i < 6; i++)
{
ChartArea.DataSeries.First().Add(new DataPoint(i, 0.01 * i));
}
for (int i = 6; i < 10; i++)
{
ChartArea.DataSeries.First().Add(new DataPoint(i, -0.01 * i));
}
Hi,
Indeed, this is a bug in RadChart. Our developers are already aware of it and the fix will appear in the next version of the control.
