Hi, I'd like to know if it is possible to control size of subplots let say control the ratio between x and y axis in length units (not in units of x and y). For example, I'd like to plot 2 graphics with one rectangular ratio y:x 1:3 and the second squared 1:1. example : import pylab x = pylab.nx.mlab.rand(10) y = pylab.nx.mlab.rand(10) ax=pylab.subplot(121) ax.scatter(x,y) #set_aspect is for x and y units not geometrical dimension of the subplot... #ax.set_aspect(3) pylab.subplot(122) pylab.scatter(x,y) pylab.show()
