[vtkusers] vtkSpiderPlotActor labels are too small

[HansAusBremen]

Hi again,

I still don't get the labels bigger and thought interaction could be a
workaround but I don't know how to switch it on.
As default the spiderplot seems not to react to interaction. I found a
method with the name "DragableOn()" and thought it would solve my problem
but it didn't.
