 [Matplotlib-users] Same X and Y scale From: Nikolaus Rath - 2010-07-30 19:34:47 ```Hi, Consider this: X = np.linspace(0.70, 1.1, 100) Y = np.linspace(-1.19, 1.19, 70) (Xs, Ys) = np.meshgrid(X, Y) Z = np.sqrt((Xs-0.9)**2 + Ys**2) - 0.10 fig = plt.figure() ax = fig.add_subplot(111) ax.contour(X, Y, Z) fig.show() This works, but gives the y axis a different scale than the x axis so the ellipses look like circles. How can I get the same scale for the x- and y-axis? I tried to set ax.set_autoscale_on(False), but that resulted in a totally different part of the coordinate system being shown.
