<P><FONT SIZE=2 FACE="Arial">Hi vtkusers,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I color my objects using vtkUnsignedCharArray instead of vtkLookUpTable. To create a vtkScalarBarActor, I have to do</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial"> scalarBar->SetLookupTable(mapper->GetLookupTable());</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">However, I have never created any lookup table explicitly, so my scalar bar always shows a color spectrum from Red to Blue. My questions are: Do I have to explicitly create a lookup table to reflect my custom color scheme? How do I let my scalar bar show my custom color scheme defined by vtkUnsignedCharArray?</FONT></P>
