That's sort of what I mean Chris and what you've suggested is what I've done for the majority of the image. It's just this particular bit which is a wiggley bent line with graduated red through to blue and a yellow line running through it. When I get home I'll post the bit I mean and you can see what you think. I'm probably trying to make things too complicated as usual. Lisa.
