[vtkusers] What is the correct way to use vtkAxisActor2D SetRange

[Burlen Loring]

Hi,
I am using python.

I have positioned the axis objects to be along side of my contour plots. In 
this case the axis is a vertical one. 

When I use the SetRange of the AxisActor2D what I get doesn't corespond to 
what I sent in as the range. I call set range with the output of GetBounds(). 
for example:

SetRange(-15.26998233795166, 14.528364181518555)

and I get -20 to 20 on the screen. 

This is a problem since I have positioned the axis actor so that it is the 
same length as the plot and the plot bounds are -15 to 14.

The behavior of the horizontally positioned one is similar but the output 
range is not the same even though the call to SetRange has the same 
arguments.

Does any one know how to use these actors to provide axis to a plot??
