Matplotlib: Change Figure Background Using fig.patch.set_facecolor()

In this tutorial, we will use an example to show you how to change figure background using fig.patch.set_facecolor() in matplotlib.

1.Load data for matplotlib plot

We will use tutorial in

to draw a plot.

PRCP = weather_data['PRCP']
TMAX = weather_data['TMAX']
TMIN = weather_data['TMIN']

2.Create a figure in matplotlib

fig = plt.figure()

3.Set background color for figure

fig.patch.set_facecolor('blue')
fig.patch.set_alpha(0.6)

In this code, we use fig.patch.set_facecolor() to set the background color of figure to blue.

Of course, you also can use fig.patch.set_alpha() to set the alpha of the figure.

4.Display plot

ax = fig.add_subplot(111)
ax.patch.set_facecolor('orange')
ax.patch.set_alpha(1.0)

plt.scatter(TMIN, PRCP)
plt.show()

In this code, we also set the background of axes.

Run this code, you will see this plot:
