使用seaborn联合图绘制统一的背景颜色

Question

When using seaborn.jointplot with a Kernel Density Estimation, the background of the KDE does not span the whole background of the figure, resulting in ugly white margins, as shown here:

Curiously, this only happens when I use stat_func=None . This is my calling command:

sns.jointplot(x=data[:,1], y=data[:,2], 
    kind="kde", space=0, color='blue', stat_func=None);

Ideally, I would like to have the blue background cover all the background so that I could also use xlim and ylim keywords. Alternatively, if I could crop the margins to where the KDE extends, it would suffice.

Answer 1

正如评论中提到的，通过joint_kws={'shade_lowest':False}解决了这个问题。
