Thank you very much!

I add a Line to the chart,then add some points to the Line.
But the Series was drawed as straigth line between points.
How can I get the Series drawed with curve between points.

Best Regards

Thank you very much!

For Example:
1.I add 300 points to Series1.
2.Then I Check the "Series--Point---Visible".
There are so many points that points overlap each other.
So I want to show "Point" every several points to avoid overlapping.

Thanks.

How to avoid overlapping when checking "Series-Point-Visible"?
"Marks" can be drawed every several points by setting the "Series--Marks--Draw every:".

Thanks.

Thanks

Anyway ,thanks for your help!
