如何在 Python Seaborn 包中更改图形的大小

Question

I'm having trouble increasing the size of my plot figures using Seaborn (imported as sns ). I'm using sns.pairplot to plot columns of a data frame against one another.

    %matplotlib inline
    plt.rcParams['figure.figsize']=10,10
    columns=list(df.columns.values)
    g=sns.pairplot(df, kind='reg', x_vars=columns,y_vars = ['Column 1'])

The plots populate with data just fine, but the figure size is too small.

I thought plot.rCParams['figure.figsize'] would control how large the figure is, but it doesn't seem to take effect. I've tried a few different suggestions from online boards, but nothing seems to work.

Answer 1

sns.pairplot "Returns the underlying PairGrid instance for further tweaking" ...for instance changing the figure size:

g=sns.pairplot(df, kind='reg', x_vars=columns,y_vars = ['Column 1'])
g.fig.set_size_inches(15,15)

Answer 2

尝试将大小放在括号中，这对我有用：

plt.rcParams['figure.figsize']=(10,10)

Answer 3

In addition to the well working answer by @MartinAnderson , seaborn itself provides the option to set the height of the subplots of the grid. In combination with the aspect this determines the overall size of the figure in dependence of the number of subplots in the grid.

In seaborn <= 0.8.1:

g = sns.pairplot(..., size=10, aspect=0.6)

In seaborn >= 0.9.0:

g = sns.pairplot(..., height=10, aspect=0.6)

Note that this applies to all seaborn functions which generate a figure level grid, like pairplot , relplot , catplot , lmplot and the underlying PairGrid or FacetGrid .

For other seaborn plots, which directly plot to axes, the solutions from How do you change the size of figures drawn with matplotlib? will work fine.

Answer 4

If we would like to change only the height or only the width then you can do

g = sns.pairplot(df, kind='reg', x_vars=columns,y_vars = ['Column 1'])
g.fig.set_figheight(6)
g.fig.set_figwidth(10)

Answer 5

您可以使用 set 进行样式控制： https ://seaborn.pydata.org/generated/seaborn.set.html

sns.set(rc={'figure.figsize':(20,10)})

Answer 6

Reffering to Rahul's question about sns.catplot ( Unable to change the plot size with matplotlib and seaborn )

If you try in jupyter notebook:

plt.figure(figsize=(25,20))
sns.boxplot(x='CriticRating', y='AudienceRating', data=movies)

it is working, but

sns.boxplot(x='CriticRating', y='AudienceRating', data=movies)
plt.figure(figsize=(25,20))

is not working (plot is very small). It's important to add line plt.figure(figsize=(25,20)) before sns.boxplot() and include %matplotlib inline of course in order to display plot in jupyter.

Answer 7

You can use set for style control : https://seaborn.pydata.org/generated/seaborn.set.html

We can accomplish this using sns.set() For example:

sns.set(rc={'figure.figsize':(20,10)})

Though, the preferred syntax is:

sns.set_theme()

NB: sns.set() or sns.set_theme() is a high level command that will set the (parameters) for everything else in your notebook.

sns.set(rc={'figure.figsize':(20,10)}) will set this to be the figure size for everything else in your notebook
