I think I have found the problem: I had thought that it was a stacked area chart + a line. It is actually an area chart with a line, therefore when I have multi-series area data, the colors of the plot areas all blend together (which I don't want). So, can you tell me if you have a combination chart consisting of a stacked area + line? And if you don't, could you develop one and how long would that take?
Many thanks.
