cbticlabels

EXPERIMENTAL (details may change in a future release version) 2D plots: colorbar labels are placed at the palette coordinate used by the plot for variable coloring "lc palette z". 3D plots: colorbar labels are placed at the z coordinate of the point. Note that in the case of a 3D heat map with variable color that does not match z, this is probably not the correct label. See also plot using xticlabels.
