[vtkusers] vtkAxisActor2D problem

I am using the vtk 4.2 distribution on Win-XP. I found a possible little
issue on  vtkAxisActor2D.
If I set the axis range with ->SetRange(0.5,1.523) for 4 Ticks and 'nice'
value distribution, the axis ticks are marked 0.0, 1.0, 1.5, 2.0. The 'end'
of the axis is marked 2.0 instead of the 1.5 tick mark being close to the
end. This means of course that the tick-marks don't line up with the data
values anymore.
I assumed from the docs that the SetRange() call  is used to tell
vtkAxisActor2D the equivalent data range along its length. 

What am I doing wrong?
