Graduated colour bars to display progress or changing values.

It is very easy in any decent 'Paint' program ( I use GIMP) to draw graduated fills and other patterns. By putting this as a background and masking it with a solid rectangle ( usually this will be white or black) at a calculated sideways distance you can generate very smart bar displays.
