the only way I have seen to get this type of charting, is to overlay two charts. And make sure the top one has a transparent background.
One chart is a scatter, the other chart is the line.
You need to makesure that both axes have the same ranges.
There are a couple of demo's floating around I have seen doing this. They probably came out when FM12 was released.
Hi Jerry, thanks so much for the reply, I will give that a go and see how it looks!
