index out of range error

[.net]

Hello,
I am using the chart to present info from a collection,if I load a collection and it is being presented on a chart (line series) and I am pressing a point on a line than I am loading this line but with other data where the number of points is less than the previous and than I am getting an error because the chart excpects to get the point it was pressed before.
For example: I am pressing (9,20) and than loading data with only 3 points -> I get an error.
Could you please explaine me how can I init the chart each time,not to expect those points??

(I tried with the tChart1.Series[0].Clear(); but it didn't affect it)
Thanks a lot!

Hi .net,

I don't understand very much what are you trying to do, but the code below may do what are you looking for.

Code: Select all

tChart1.Series[0].Delete(0,tChart1.Series[0].Count-1);

After having deleted all original series points then you can repopulate again.

Hello,
it's not helping.
I still gret an error - it happens when I load a data to a line then click on the line in some point (for example 10,20) and than load a new line on this chart which doesn't have points in those coordinates(it shorter).
How can I solve this?
Maybe I can scroll it some way to the beggining of the chart?
Thank you!
