Python Matplotlib figure title overlaps axes label when using twiny


I am trying to plot two separate quantities on the same graph using twiny as follows:

fig = figure()
ax = fig.add_subplot(111)
ax.plot(T, r, 'b-', T, R, 'r-', T, r_geo, 'g-')
ax.annotate('Approx. sea level', xy=(Planet.T_day*1.3,(Planet.R)/1000), xytext=(Planet.T_day*1.3, Planet.R/1000))
ax.annotate('Geostat. orbit', xy=(Planet.T_day*1.3, r_geo[0]), xytext=(Planet.T_day*1.3, r_geo[0]))
ax.set_xlabel('Rotational period (hrs)')
ax.set_ylabel('Orbital radius (km), logarithmic')
ax.set_title('Orbital charts for ' + Planet.N, horizontalalignment='center', verticalalignment='top')

ax2 = ax.twiny()
ax2.set_xlabel('Linear speed (ms-1)')


and the data is presented fine, but I am having the problem that the figure title is overlapping with the axes labels on the secondary x axis so that it’s barely legible (I wanted to post a picture example here, but I don’t have a high enough rep yet).

I’d like to know if there’s a straightforward way to just shift the title directly up a few tens of pixels, so that the chart looks prettier.

Forget using plt.title and place the text directly with plt.text. An over-exaggerated example is given below:

import pylab as plt

fig = plt.figure(figsize=(5,10))

figure_title = "Normal title"
ax1  = plt.subplot(1,2,1)

plt.title(figure_title, fontsize = 20)

figure_title = "Raised title"
ax2  = plt.subplot(1,2,2)

plt.text(0.5, 1.08, figure_title,
         transform = ax2.transAxes)

I’m not sure whether it is a new feature in later versions of matplotlib, but at least for 1.3.1, this is simply:

plt.title(figure_title, y=1.08)

This also works for plt.suptitle(), but not (yet) for plt.xlabel(), etc.

ax.set_title('My Titlen', fontsize="15", color="red")
plt.imshow(myfile, origin="upper")

If you put 'n' right after your title string, the plot is drawn just below the title. That might be a fast solution too.

I was having an issue with the x-label overlapping a subplot title; this worked for me:

import matplotlib.pyplot as plt
fig, ax = plt.subplots(2, 1)

Just use plt.tight_layout() before It works well.

You can use pad for this case:

ax.set_title("whatever", pad=20)

A temporary solution if you don’t want to get into the x, y position of your title.

Following worked for me.

plt.title('Capital Expendituren') # Add a next line after your title
