plot = sns.distplot(df[['my_column_to_plot']])
plot.savefig("myfig.png")
And I have this error:
我有这个错误：

You could use plt.savefigbecause your picture will come up when you'll call plt.show()
你可以使用plt.savefig因为当你打电话时你的照片会出现plt.show()
回答by galucero
Use plt.savefig('yourTitle.png')
用 plt.savefig('yourTitle.png')
If you want to pass a variable:
如果你想传递一个变量：
plt.savefig("yourTitleDataSet{0}.png".format(dataset))

You could save any seaborn figure like this.
你可以像这样拯救任何海生人物。
Suppose If you want to create a violin plot to show the salary distribution gender wise. You could do it like this and will save it using the get_figure method.
假设如果你想创建一个小提琴图来显示性别明智的工资分配。您可以这样做，并使用 get_figure 方法保存它。
ax = sns.violinplot(x="Gender", y="Salary", hue="Degree", data=job_data)
#Returns the :class:~matplotlib.figure.Figure instance the artist belongs to
fig = ax.get_figure()
fig.savefig('gender_salary.png')
