Description

For me (on RHEL6), performing the following steps crashes MantidPlot:

  • Load a dataset
  • Plot as a color fill plot
  • Double-click inside the plot to bring up the Plot Details dialog
  • Select UserHelperFunction and the Colors tab
  • Select Custom color map and choose a map
  • Click Apply
  • Boom!

Re #5599. Be a bit more general when accessing vector member.

Although the documentation for QwtColorMap::colorTable says that it should return a vector of length 256, in the case of our colormaps it can be shorter, it would seem.
