        It looks like there are only a fixed number of colours available, and the colours don't smoothly move with the values--is that true? Would it be difficult to have rainbow colours with smoothly scaled colours?

        Sorry I misunderstood the code, I was reading the bit that generates the legend, I like the rainbow colours.

        +1 for the patch.
