[vtkusers] vtkChartXY

[Hagen Mölle]

Hi Marcus and Eric,

I am sorry, I was wrong. The code is ok.

#Another problem that I will fix:

#When removing a plot by index the following code will be executed 
#additionally (vtkChartXY.cxx:864).

#// Ensure that the bounds are recalculated
#this->PlotTransformValid = false;
#// Mark the scene as dirty
#this->Scene->SetDirty(true);

#When removing a plot by using a vtkPlot pointer this code is missing 
#(vtkChart.cxx:75). Therefore I will overwrite 
#RemovePlotInstance(vtkPlot* plot) in vtkChartXY to accomplish this.
