Create symmetric figures when using matplotlib labels

Question

I am using plt.subplots with both ax.set_ylabel and fig.supylabel. However, this creates figures that are off-centered.

Is it possible to automatically increase the right margin such that the red line is at the center of the figure? In the case I am doing this manually, how can I precisely measure by how much I should increase the right margin?

Answer 1

How about this:

fig = plt.figure()
ax1 = fig.add_subplot(1,2,1)
ax2 = fig.add_subplot(1,2,2)
x = np.arange(50)
ax1.plot(x,np.sin(x))
ax2.plot(x,np.sin(x))
ax1.set_ylim(-1,1)
ax2.set_ylim(-1,1)
ax2.set_yticklabels('')
ax1.set_title('damped')
ax2.set_title('undamped')
ax1.set_ylabel('amplitude')
fig.suptitle('Different types of oscillations')

Output:

---edit---

Try this:

import matplotlib.gridspec as grd

fig = plt.subplots()

gs = grd.GridSpec(1, 2, wspace=0.5)
ax1 = plt.subplot(gs[0])
ax2 = plt.subplot(gs[1])

x = np.arange(50)
ax1.plot(x,np.sin(x))
ax2.plot(x,np.sin(x))

ax1.set_title('damped')
ax2.set_title('undamped')
ax1.set_ylabel('amplitude')

The keypoint is gs = grd.GridSpec(1, 2, wspace=0.5). Adjust wspace as you like. The plot below is for wspace=0.5
