[vtkusers] Changing the font size of vtkXYPlotActor

[Mathieu Coursolle]

Hi VTK users,

I am using vtkXYPlotActor to display some data, which is working fine.  
However, I would like the title and axis title to be smaller. Calling  
GetTextProperty()->SetFontSize() does not seems to work, as the titles  
are scaled to the view size.

Is there a way to specify the font size, or to let it scale, but with  
a smaller ratio?

Thank you.
Mathieu
