How do I change the size of figures drawn with Matplotlib in Python?
To set the size of a new figure on creation, you can provide the figsize
keyword argument. This will be a tuple of the desired width and height in inches.
myfigure = figure(figsize=(18, 10), # additional arguments... )
To set the size of a figure that’s already been created, use the set_size_inches()
method. This method takes a new width and height in inches:
myfigure.set_size_inches(18, 10, forward=True)
The forward=True
argument will propagate the size change to any currently displayed versions of the figure.
If you only want to change the height or width of a figure, you can use set_figwidth()
or set_figheight()
.
By default, an inch is 100 pixels in length. You can use set_dpi()
to change this.
When working with a plot rather than a figure, you can use rcParams
:
import matplotlib.pyplot as pyplt pyplt.rcParams["figure.figsize"] = (18, 10)
Note that this will determine the size of all subsequently created plots.
