matplotlib: Aligning y-axis labels in stacked scatter plots

Question

In the plot bellow i have two scatter plots which have different number scale, so their Y-axis labels are not aligned. Is there any way I can force the horizontal alignment in the y-axis labels?

import matplotlib.pylab as plt import random import matplotlib.gridspec as gridspec  random.seed(20) data1 = [random.random() for i in range(10)] data2 = [random.random()*1000 for i in range(10)]  gs = gridspec.GridSpec(2,1) fig = plt.figure()  ax = fig.add_subplot(gs[0]) ax.plot(data1) ax.set_ylabel(r'Label One', size =16)  ax = fig.add_subplot(gs[1]) ax.plot(data2) ax.set_ylabel(r'Label Two', size =16)  plt.show() 

Answer 1

You can use the set_label_coords method.

import matplotlib.pylab as plt import random import matplotlib.gridspec as gridspec  random.seed(20) data1 = [random.random() for i in range(10)] data2 = [random.random()*1000 for i in range(10)]  gs = gridspec.GridSpec(2,1) fig = plt.figure()  ax = fig.add_subplot(gs[0]) ax.plot(data1) ax.set_ylabel(r'Label One', size =16) ax.get_yaxis().set_label_coords(-0.1,0.5)  ax = fig.add_subplot(gs[1]) ax.plot(data2) ax.set_ylabel(r'Label Two', size =16) ax.get_yaxis().set_label_coords(-0.1,0.5)
