George, The problem with your attempt to use get_position() is that the aspect ratio does not affect the position until the apply_aspect method of the axes is called, which is normally when drawing occurs. You can either call it yourself, or you can insert a draw command. Here is an example of the first: In [6]:pcolor(z) Out[6]:<matplotlib.collections.PolyCollection instance at 0xb3db690c> In [7]:gca().get_position() Out[7]:[0.125, 0.099999999999999978, 0.77500000000000002, 0.80000000000000004] In [8]:gca().set_aspect(3) In [9]:gca().get_position() Out[9]:[0.125, 0.099999999999999978, 0.77500000000000002, 0.80000000000000004] In [10]:clf() In [11]:pcolor(z) Out[11]:<matplotlib.collections.PolyCollection instance at 0xb3dc6a6c> In [12]:gca().get_position() Out[12]:[0.125, 0.099999999999999978, 0.77500000000000002, 0.80000000000000004] In [13]:gca().set_aspect(3) In [14]:gca().apply_aspect() In [15]:gca().get_position() Out[15]: [0.31343312597200623, 0.099999999999999978, 0.39813374805598761, 0.80000000000000004] Eric ------------------------------------------------------------------------- Take Surveys.
