Maybe this is too much magic, but could you look at what was passed in to the subplot call: I don't remember if you are following the figure.add_subplot() api, but: If nothing, then the user is clearly asking for a single axis. if (r,c,n) then the user is specifying a 2-d arrangement, even if r and c happen to be 1. I think the only two options should be scalar or 2-d array, it seems a bit much to have a 1-d array option as well. Also, IIUC correctly, Figure.add_subplot always returns a SINGLE axis -- you have to call it multiple times to get the whole set. Does this version return the whole set? -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
