<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I am a bit confused about following behaviour. I tried to find an answer / solution, but spent already more than a day with that. Maybe the behaviour is correct, I just misunderstand
it?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I have a point cloud (VtkPolyData), using a VtkTransform Filter to scale the z-values. As I want the points to be displayed colored, I use the vtkLookupTable as well as the ScalarBarWidget
to display the lookup table.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Before scaling my z-range is 98 – 255, after scaling (2*) the range is 196 – 510.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">If I do not change the VtkLookupTable’s table range (it is still 98 – 255), the colors are mapped correctly from 196 to 510. If I change the table range to 196 – 510 and the
mapper’s scalar range to 196 – 510, in order to get a correct valued ScalarBarWidget (range 196 – 510), only colors from 196 to 255 are mapped, everything else not. (The picker shows the correctly scaled point data.)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">My questions: Why is the mapping wrong if I update the scalar range / lookup table range? How can I achieve a correctly scaled ScalarBarWidget (196 – 510)?<o:p></o:p></span></p>
