Python、Seaborn FacetGrid 更改标题

问题描述

我正在尝试在 Seaborn 中创建一个 FacetGrid

I am trying to create a FacetGrid in Seaborn

我的代码目前是:

g = sns.FacetGrid(df_reduced, col="ActualExternal", margin_titles=True)
bins = np.linspace(0, 100, 20)
g.map(plt.hist, "ActualDepth", color="steelblue", bins=bins, width=4.5)

这给了我的图

现在，我想要标题内部"和外部"，而不是ActualExternal =0.0"和ActualExternal =1.0"

Now, instead of "ActualExternal =0.0" and "ActualExternal =1.0" I would like the titles "Internal" and "External"

而且，我希望xlabel代替"ActualDepth"说"Percentage Depth"

And, instead of "ActualDepth" I would like the xlabel to say "Percentage Depth"

最后，我想添加一个缺陷数"的 ylabel.

Finally, I would like to add a ylabel of "Number of Defects".

我尝试了谷歌搜索，并尝试了一些方法，但到目前为止没有成功.请问你能帮我吗?

I've tried Googling and have tried a few things but so far no success. Please can you help me?

谢谢

推荐答案

您可以通过 g 访问 FacetGrid (g = sns.FacetGrid(...)) 的轴.轴.有了它，您可以自由使用任何您喜欢的 matplotlib 方法来调整绘图.

You can access the axes of a FacetGrid (g = sns.FacetGrid(...)) via g.axes. With that you are free to use any matplotlib method you like to tweak the plot.

更改标题:

axes = g.axes.flatten()
axes[0].set_title("Internal")
axes[1].set_title("External")

更改标签:

axes = g.axes.flatten()
axes[0].set_ylabel("Number of Defects")
for ax in axes:
    ax.set_xlabel("Percentage Depth")

请注意，我更喜欢 FacetGrid 的内部 g.set_axis_labels 和 set_titles 方法之上的那些，因为它使哪些轴更加明显是要贴标签的.

Note that I prefer those above the FacetGrid's internal g.set_axis_labels and set_titles methods, because it makes it more obvious which axes is to be labelled.
