Python - save a figure with the same size and setting

Question

I plot figures a lot during my python (through Spyder env.) usage. However, when I try to use plt.savefig('figure.png'), the saved figure has a different size from the inline figure plotted on Spyder.

For ex., when I use this command:

 plt.savefig('fig1.png')

The saved figure looks like this:

Note that there's something weird with the saved figure, e.g.: the title is cropped, the size is not proportional.

However, the following is the inline figure:

I tried to modify the size through matplotlib.pyplot documentation but couldn't find such setting. Does anyone know how to save the figure with the exact setting as the inline plot?

Answer 1

The inline figure size plotted in Spyder (or any other IDE or editor) depends on how the editor handles showing figures.

If you want to have an exact size as output of your code, use figsize before plotting code. (It uses inches)

import matplotlib.pyplot as plt

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

# Code to produce figure

You can also determine DPI when creating figure or saving.

plt.figure(figsize=(10, 10), dpi=300)

# or

plt.savefig(file_path, dpi=300)
