Chart: get width on runtime

I use a Line-Chart and I want to make it possible to "zoom in" with a MouseDown and MouseUp-Event.
(I know its possible to make a "SeriesClick" but my testers find it very hard to hit the right point.)
The two mouse-events (down and up) runs perfectly and I get with the "MouseEventArgs " the "args.OffsetX".
To calculate the DateTime-value on the x-axis (in SeriesClick its the "args.Category") I need the width of the LineChart,
It would be very nice if someone had an idea how I can get it.
With best regards,

Hi @R_Resch,

The width isn't available. You can check the source code to see how the SeriesClick event is implemented. Perhaps you can use the available API or get inspired by the implementation.
