You can achieve a constant axes sizes by addind the axes manually.
In my code example I introduce an scale factor
sc which determines the ratio of figure and axes size.
import matplotlib.pyplot as plt gr = (1 + np.sqrt(5))/2 sc = 2 fig_w = 3 * gr * sc fig_h = 3 * sc fig = plt.figure(figsize=(fig_w, fig_h)) panel_width = 1/sc panel_height = 1/sc off = (1 - 1/sc) / 2 ax = fig.add_axes([off, off, panel_width, panel_height]) ax.plot([-1, -4.5, 16, 23, 15, 59])
