Stop seaborn plotting multiple figures on top of one another
Create specific figures and plot onto them:
import seaborn as sns
iris = sns.load_dataset('iris')
length_fig, length_ax = plt.subplots()
sns.barplot(x='sepal_length', y='species', data=iris, ax=length_ax)
length_fig.savefig('ex1.pdf')
width_fig, width_ax = plt.subplots()
sns.barplot(x='sepal_width', y='species', data=iris, ax=width_ax)
width_fig.savefig('ex2.pdf')
You have to start a new figure in order to do that. There are multiple ways to do that, assuming you have matplotlib
. Also get rid of get_figure()
and you can use plt.savefig()
from there.
Method 1
Use plt.clf()
import seaborn as sns
import matplotlib.pyplot as plt
iris = sns.load_dataset('iris')
length_plot = sns.barplot(x='sepal_length', y='species', data=iris)
plt.savefig('ex1.pdf')
plt.clf()
width_plot = sns.barplot(x='sepal_width', y='species', data=iris)
plt.savefig('ex2.pdf')
Method 2
Call plt.figure()
before each one
plt.figure()
length_plot = sns.barplot(x='sepal_length', y='species', data=iris)
plt.savefig('ex1.pdf')
plt.figure()
width_plot = sns.barplot(x='sepal_width', y='species', data=iris)
plt.savefig('ex2.pdf')
I agree with a previous comment that importing matplotlib.pyplot
is not the best software engineering practice as it exposes the underlying library. As I was creating and saving plots in a loop, then I needed to clear the figure and found out that this can now be easily done by importing seaborn
only:
since version 0.11:
import seaborn as sns
import numpy as np
data = np.random.normal(size=100)
path = "/path/to/img/plot.png"
plot = sns.displot(data) # also works with histplot() etc
plot.fig.savefig(path)
plot.fig.clf() # this clears the figure
# ... continue with next figure
alternative example with a loop:
import seaborn as sns
import numpy as np
for i in range(3):
data = np.random.normal(size=100)
path = "/path/to/img/plot2_{0:01d}.png".format(i)
plot = sns.displot(data)
plot.fig.savefig(path)
plot.fig.clf() # this clears the figure
before version 0.11 (original post):
import seaborn as sns
import numpy as np
data = np.random.normal(size=100)
path = "/path/to/img/plot.png"
plot = sns.distplot(data)
plot.get_figure().savefig(path)
plot.get_figure().clf() # this clears the figure
# ... continue with next figure
