This has been fixed on the development branch which is about to become release 3.8 within the next two weeks. Attached are pngs from 3.6.4 (wrong) and 3.8 (right) done with the FLTK toolkit.

While trying to plot topographical maps of significance-levels, I noticed that there are cases where the labelling of the colour bar and what actually appears in the plot don't match very well, especially when using a small number of colours.

Here is a simple test case:

Judging from the colourbar, only the blocks containing 1 and 2 should be assigned the same colour (dark blue), but in the image, the blocks containing 2 and 3 as well as those containing 7 and 8 are assigned the same colours, and the block containing 9 is assigned the wrong colour.

This behaviour is reproducible with 3.6.3 on Fedora, 3.6.4 on Lubuntu, and 3.6.1 on OSX.
