In order to arrange the plots I would like to split the figure into two (or more) panels and within each of them create a nested set of subplots. Optimally, the main panels should define their own coordinate systems, such that all of the nested subplot positions are defined within their frame. The syntax could look like that: > > panel1 = subplot(1,2,1) > panel2 = subplot(1,2,2) > > ax1 = panel1.add_subplot(1,2,1) > ax2 = panel1.add_subplot(1,2,2) > > ax3 = panel2.add_subplot(111)
I think what you could maybe try is to write a class using figure.add_axes() http://matplotlib.sourceforge.net/api/figure_api.html#matplotlib.figure.Figure.add_axes The class could store a relative area and a "master". For the panels you need, the master would be the Figure. Such a Panel class could expose an add_axes() method too, but forwarding the call to its master. To calculate the *rect* argument when callings its master's .add_axes(), it would use a linear transformation from the stored extent to the (0, 1) extent relative to the master. Let it be depicted: +----------------------+ Figure +-------------+ Panel +------+ Axes There could be more Panels in between. You would do: >>> panel = Panel(figure, (0.2, 0.6)) # left = 0.2, width = 0.6, i.e. right = 0.8 >>> axes = panel.add_axes((0, 0.5)) # left = 0, width = 0.5, i.e. right = 0.5 The last call would do: 1) Transform the (0, 0.5) to the Figure reference frame (more precise, to the master ref frame, where by coincidence the Figure is the master). Thie yields here (0.2, 0.3) = (left, width), i.e. right = 0.5 (in the master ref frame). 2) Call master.add_axes((0.2, 0.3)). This actually creates the Axes instance by recusions until the master is a Figure. I think this approach is feasible in < 200 loc. hth Friedrich
