[vtkusers] simple scalar bar question.....

[nikhil butala]

Dear VTK Users,
 
                 In my application, By default VTK assigns red color to 0(zero) value and blue color to the maximum value in scalar bar. 
Does anyone know a simple method to reverse this. i.e. give blue color to zero value and red to maximum value??
 
thanks,
Nikhil Butala
