MS Chart Control .NET 3.5

[C# Programming]

Hello.

I'm trying to use CursorX and CursorY in MS Chart Control .NET 3.5, but somehow I didn't find any help in documentation.
Does somebody know how to do this ? :

1. I use CursorX and CursorY, then I want to make it gone (deactivate) it, but the CursorX and CursorY are still there.
IsUserEnabled=false, IsUserSelectionEnabled=false.
******* or Invalidate didn't help. Anybody know how to deactivate it, or make it gone ?

2. If I use CursorX and CursorY, they also draw a cursor, which point doesn't exists.
For example, my point are : 1;1 2;2 5;5
The cursor must be active only at that points, but MSChart activate also at point 3;3 4;4
How to disable this ?

Thanks...
