Why can't you simply draw a 3 - D plot. The third variable being categorical can expressed as a bar.

I have 100 points on a simple xy-plot. The points are distinguished by a third variable which is categorical with 10 levels. I have been plotting x against y and using gray scales to distinguish the level of the categorical variable for each point. It looks ok to me but a journal reviewer says this is not any use. I cannot afford to pay for colour prints. Any ideas on what is the best way to distinguish 10 groups on an xy scatter plot? If all else fails I can just remove the graph and give them a table of regression coefficients. Thanks.
