[vtkusers] Remove all plots from vtkChartXY

[Jothy]

I put the vtkChartXY setting (axis min,max,behaviour,etc..) in the class
constructor. Now it works fine.

Thanks for your suggestions!

Do you know how to to format the labels. (I mean the one which popsup when
the mouse hovers over the line). Right now I see e.g.,Plot1:
10.0676,70.009456 I want only two decimal places.

Thanks

Jothy
