Hi,<br><br>I am having some trouble with the vtkScalarBarActor (Java + vtk 5.1.0 )<br><br><br>When using a linear scale in my lookup table:<br><br> vtkLookupTable lut = new vtkLookupTable();<br><br> lut.SetNumberOfColors
(1024);<br> lut.SetHueRange(0.15, 1.0);<br> lut.SetSaturationRange(1.0, 1.0);<br> lut.SetValueRange(1.0, 1.0);<br> lut.SetAlphaRange(1.0, 1.0);<br> lut.SetScaleToLinear();<br><br>The actor behaves. Colours and labels are fine.
<br><br>But if I set:<br><br>lut.SetScaleToLog10();<br><br>I get a single colour ( yellow ) and NAN across the scalar bar<br><br>Does the scalar bar work for Log10 ?<br><br>Is there some no-brainer that I have missed?<br>
