Alan, I've had a quick look at this. It is something I've desired for a while so it is great to see it! A few random thoughts. 1) This is great for non-interactive uses. For interactive use you may not know in advance how many legend entries there are. It would be nice to add entries as you go along. This is a lot more complicated, and may well not be worth the effort. It doesn't fit with the plplot design very neatly. How does plplot cope with multiple calls to pllegend if you update the legend as you go? 2) A different, but related, issue is colourbars for colour contour plots. Support for this would also be good. 3) I'm not quite sure from the examples or what you have said whether a legend outside the plot is possible, but I certainly think it should be. Overall I think the current API is probably fit for most uses.
