hi all, i am drawing a 2x3 set of subplots. i want it to eliminate the second subplot of the first row and instead make the first subplot on the first row take up two plots worth of space, i.e. have it so that the first subplot takes up 2,3,1 and 2,3,2. In matlab, the command would be something like subplot(2,3,[1,2]). what is the way to do this in matplotlib? i have a lot of code structured subplots and subplots_adjust, and i really want to avoid switching to drawing my own axes if possible, as in this example: http://matplotlib.sourceforge.net/examples/axes_grid/simple_axes_divider1.html switching to this would be very complicated  is there a way to do this while still using the subplot command? thanks.

There a few work around you may try, but it will at least take a few tens of lines of code. Attached is a way to do this by patching the object method, which I personally do not prefer but may be one of the easiest for normal users. Also, there is a patch I once worked on, but haven't pushed into the svn yet (i'm not sure if I ever will). So give it a try if you want. http://article.gmane.org/gmane.comp.python.matplotlib.general/19097 Regards, JJ import matplotlib.transforms as mtransforms def expand_subplot(ax, num2): update_params_orig = ax.update_params ax._num2 = num2  1 def _f(self=ax): num_orig = self._num self._num = self._num2 update_params_orig() right, top = self.figbox.extents[2:] self._num = num_orig update_params_orig() left, bottom = self.figbox.extents[:2] self.figbox = mtransforms.Bbox.from_extents(left, bottom, right, top) ax.update_params = _f ax.update_params() ax.set_position(ax.figbox) ax = subplot(231) expand_subplot(ax, 2)

thanks very much. Using expand_subplot for that purpose worked great, but I am now trying a variant of this and am having trouble getting it to work. I'd like to create a subplot that has two parts: the left part is a square plot, and the right part is a 2x2 set of square subplots. Something like this: http://www.mathworks.com/access/helpdesk_archive_ja_JP/r2007/help/toolbox/matlab/ref/image/subplot_vert.gif Except the left hand plot should have square axes. just imagine taking a square plot and putting it on the left, and then making a 2x2 subplot, which each subplot is less than 1/4 the size of the square plot on the left, and putting that on the right hand panel. is there a way to do this in matplotlib? thanks.
