改变seaborn配对图中的标记大小与种类reg

Question

I want to reduce marker size in seaborn 0.9.0 pairplot using kind = 'reg'

I have tried:

sns.pairplot(a_dataframe, kind="reg", s=1)
TypeError: pairplot() got an unexpected keyword argument 's'

sns.pairplot(a_dataframe, kind="reg", scatter_kws={'s':2})
pairplot() got an unexpected keyword argument 'scatter_kws'

sns.pairplot(a_dataframe, kind="reg", plot_kws=dict(s=1))
regplot() got an unexpected keyword argument 'plot_kws'

Answer 1

You have to chain the kwargs, first to pass them on to sns.regplot , which is used to plot the off-diagonal plots. sns.regplot itself accepts a scatter_kws= argument to be passed to plt.scatter() which is the function that actually draws the scatter plot.

iris = sns.load_dataset("iris")
g = sns.pairplot(iris, kind="reg", plot_kws=dict(scatter_kws=dict(s=2)))
