>From the vtk "Histogram.tcl" example:

    vtkImageViewer viewer2
      viewer2 SetInput [magnify GetOutput]
      viewer2 SetZSlice 14
      viewer2 SetColorWindow 2000
      viewer2 SetColorLevel 1000
    [...]

Perhaps you need to set your color window and level?
Window is the range of pixel values;
level is the center of the range.
