I have started work on the plcolorbar API. I don't expect to have it done today, but it did bring up some API/functionality changes I would like to propose for pllegend (and use in plcolorbar). 1. I think it is worth considering different ways of expressing the position of a legend or color bar. For example, in the OCaml color bar API, the position of the color bar is specified relative to a user-specified plot subpage boundary. This could be done in the C API with another set of options for the "opt" parameter: PL_LEGEND_TOP, PL_LEGEND_BOTTOM, PL_LEGEND_LEFT, PL_LEGEND_RIGHT and possibly PL_LEGEND_CENTER. The position arguments would then be interpreted as offsets from the given side. For example: PL_LEGEND_BOTTOM | PL_LEGEND_RIGHT : Position the box relative to the bottom-right of the plot subpage PL_LEGEND_RIGHT | PL_LEGEND_CENTER : Position the box relative to the right side of the plot subpage, centered vertically (the y-position would be ignored in this case) The default would continue to be PL_LEGEND_TOP | PL_LEGEND_LEFT. I expect PL_LEGEND_CENTER to be more commonly used with plcolorbar. 2. Allow a user to specify if they want the legend positioned relative to the plot window or the plot subpage (PL_LEGEND_PAGE or PL_LEGEND_WINDOW?). The position would be (possibly normalized) plot window coordinates for PL_LEGEND_WINDOW and normalized subpage coordinates for PL_LEGEND_PAGE. Sizes/lengths would probably still be specified as normalized subpage coordinates. I expect most of the "opt"-appropriate options to be shared between pllegend and plcolorbar. If the rest of you feel that these changes are reasonable, I am willing to make or help make the required changes to the C implementation of pllegend.
