While working on the OCaml interface to pllegend, I came up with a potential improvement to the C interface: What do you think of changing the pllegend API somewhat to allow only specifying the entries which are actually used? For example, if there are no symbols, the symbol arrays would be empty. If there are two lines and one box, there would be two elements in the line arrays and one in the box array. nlegend would still be the total number of entries in the legend, and opt_array would be used to specify where the legend entries are placed. Here is a example subset of parameters: nlegend: 4 opt_array: PL_LEGEND_LINE, PL_LEGEND_LINE, PL_LEGEND_SYMBOL | PL_LEGEND_LINE, PL_LEGEND_LINE line_colors: red, blue, purple, green symbol_colors: blue, yellow From these (plus styles, widths, symbols, etc), the legend would show up as: 1. blue symbols, red line 2. blue line 3. yellow symbols, purple line 4. green line Does this make sense? I think it would make passing arguments to pllegend a bit more predictable as no dummy entries are required, but I don't know if others would feel the same way. I'm willing to make an attempt at implementation if you think it is worth considering.
