fig.set_figheight and fig.set_figwidth not working

Question

Why is this code not changing the size of the figure plotted?

   fig1, ax1 = plt.subplots(nrows=1, ncols=3)
   fig1.set_figheight = 30
   fig1.set_figwidth = 30
         


        

Answer 1

fig1.set_figheight = 30 assigns 30 to the .set_figheight attribute. While previously fig1.set_figheight was a method that could be used to change the height of the figure, from now on it is, well, simply 30.

The solution is simple: Use the method instead of destroying it.

fig1.set_figheight(30)

Note that because you have overwritten the method you will need to restart the kernel, such that matplotlib can be reimported and the attribute is restored to its original state.
