You can simply use (from matplotlib.figure.Figure):

fig.set_size_inches(width,height)

As of Matplotlib 2.0.0 it will even automatically update your canvas as the forward keyword now defaults to True. (For earlier versions you need to specify forward=True explicitly.)

If you want to just change the width or height instead of both, you can use

fig.set_figwidth(val)

or

fig.set_figheight(val)

Unfortunately you need to specify forward=True to automatically propagate the changes as it still defaults to False for these functions, though this is being fixed. (These functions don’t support forward in versions older than Matplotlib 1.5.0)

You can simply use (from matplotlib.figure.Figure):

fig.set_size_inches(width,height)

As of Matplotlib 2.0.0, changes to your canvas will be visible immediately, as the forward keyword defaults to True.

If you want to just change the width or height instead of both, you can use

fig.set_figwidth(val) or fig.set_figheight(val)

These will also immediately update your canvas, but only in Matplotlib 2.2.0 and newer.

For Older Versions

You need to specify forward=True explicitly in order to live-update your canvas in versions older than what is specified above. Note that the set_figwidth and set_figheight functions don’t support the forward parameter in versions older than Matplotlib 1.5.0.
