How to put the title at the bottom of a figure in matplotlib?

Question

I use matplotlib to plot a figure with four subfigures, and set_title method put the title ( (a) (b) (c) (d)) on the top of every subfigure, see the following code example.

fig = pyplot.figure()
ax = fig.add_subplot(1, 4, 1)
ax.set_title('(a)')

But I want to put every title at the bottom of every subfigure. I can't figure out it by the matplotlib document and google. So I need your help, thanks very much.

Answer 1

Please use the following line if you are using ax, then adjust the value of 'y'.

ax.set_title('(d)',y=-0.2,pad=-14)

You can adjust the y value, here I use 'negative' value because I want my label to be on the bottom of the graph within subplot.

I have not check what is pad yet.

Answer 2

Since you're not using the x axis you can just simply set the xlabel to act as the title, should take care of the positioning:

ax.set_xlabel('this really is a title disguised as an x label')

Edit:

Try offsetting the title according to the figure height, I hope this works:

size = fig.get_size_inches()*fig.dpi # get fig size in pixels
ax.set_title('(a)', y=-size) # increase or decrease y as needed
