[vtkusers] multiple charts/plots in one window

[Zoltan Takacs]

Hi,

I am trying to do what you suggested and started combining the the 
examples of scatterplot.cxx and mutipleviewports.cxx -> see the attached 
Scatterplot2.cxx file for the result. the code does compile and run and 
the window is split into 2 however the charts are missing. I am missing 
the mapper and the actor and I am not sure which one to use for 2D scene 
(with vtkChartXY). Is it necessary to have a mapper and an actor for a 
2D scene?


Thanks
