matplotlib y-axis label on right side

Question

Is there a simple way to put the y-axis label on the right-hand side of the plot? I know that this can be done for the tick labels using ax.yaxis.tick_right(), but I would like to know if it can be done for the axis label as well.

One idea which came to mind was to use

ax.yaxis.tick_right() ax2 = ax.twinx() ax2.set_ylabel('foo') 

However, this doesn't have the desired effect of placing all labels (tick and axis labels) on the right-hand side, while preserving the extent of the y-axis. In short, I would like a way to move all the y-axis labels from the left to the right.

Answer 1

It looks like you can do it with:

ax.yaxis.set_label_position("right") ax.yaxis.tick_right() 

See here for an example.

Answer 2

If you would like to follow the example given in matplotlib and create a figure with labels on both sides of the axes but without having to use the subplots() function, here is my solution :

from matplotlib import pyplot as plt import numpy as np  ax1 = plt.plot() t = np.arange(0.01, 10.0, 0.01) s1 = np.exp(t) plt.plot(t,s1,'b-') plt.xlabel('t (s)') plt.ylabel('exp',color='b')  ax2 = ax1.twinx() s2 = np.sin(2*np.pi*t) ax2.plot(t, s2, 'r.') plt.ylabel('sin', color='r') plt.show()
