[vtkusers] font size problem

[John Platt]

Hi Ian,

I am not sure if it's the plot title or axis labels you want to change.
In RenderOpaqueGeometry(), the call 

      vtkAxisActor2D::SetFontSize(viewport, 
                                  this->TitleMapper, 
                                  size, 
                                  1.0,
                                  stringSize);

uses the viewport size as the target area for the constrained title font
size. My understanding was that all composite 2D actors should 'fit'
within the plot actor.

John.

Well, my problem is the other way around actually, I am displaying as 
many as 20 continuous plots on the screen at a time, so as you can 
imagine, they are pretty small.  I am trying to figure out a way to make

the charts readable.  Do you happen to know where in the code, I could 
change the part that constrains the font size.  I'll take a look around 
myself as well.  Thanks for your help,
-Ian
