vtkXYPlotActor has not been used in ParaView for quite some time (I am not
sure if/when it was used in ParaView). The new charts were written largely
by me to replace the Qt based charts in GUISupport/Qt. The behavior of the
new charts is to clip the lines, i.e. a partial line would be drawn, ending
where the line leaves the plot area.

Is there any reason you are not using the new charts in your work? These are
being actively developed, and I would be interested in feedback on any
lacking features/bugs (have some I am currently working on).

Thanks,

Marcus
