Seaborn despine() 带回 ytick 标签

Question

这是一个代码片段

tips = sns.load_dataset("tips")
g = sns.FacetGrid(tips, col = 'time')
g = g.map(plt.hist, "tip")

输出如下

我想在这些图中引入 despine offset，同时保持其余部分不变。因此，我在现有代码中插入了despine函数:

tips = sns.load_dataset("tips")
g = sns.FacetGrid(tips, col = 'time')
g.despine(offset=10)
g = g.map(plt.hist, "tip")

结果如下图

因此，偏移量将应用于轴。然而，右图上的ytick标签又回来了，这是我不想要的。

有人可以帮我解决这个问题吗？

要删除 yaxis 刻度标签，您可以使用以下代码:

库:

import seaborn as sns
sns.set_style('ticks')

调整后的代码:

tips = sns.load_dataset("tips")
g = sns.FacetGrid(tips, col = 'time')
g.despine(offset=10)
g = g.map(plt.hist, "tip")

# IMPORTANT: I assume that you use colwrap=None in FacetGrid constructor
# loop over the non-left axes:
for ax in g.axes[:, 1:].flat:
    # get the yticklabels from the axis and set visibility to False
    for label in ax.get_yticklabels():
        label.set_visible(False)
    ax.yaxis.offsetText.set_visible(False)

更一般一点，想象一下，您现在有一个 2x2 FacetGrid，您想要使用偏移量进行缩放，但 x- 和 yticklabels 返回:

使用以下代码将它们全部删除:

tips = sns.load_dataset("tips")
g = sns.FacetGrid(tips, col = 'time', row='sex')
g.despine(offset=10)
g = g.map(plt.hist, "tip")

# IMPORTANT: I assume that you use colwrap=None in FacetGrid constructor
# loop over the non-left axes:
for ax in g.axes[:, 1:].flat:
    # get the yticklabels from the axis and set visibility to False
    for label in ax.get_yticklabels():
        label.set_visible(False)
    ax.yaxis.offsetText.set_visible(False)

# loop over the top axes:
for ax in g.axes[:-1, :].flat:
    # get the xticklabels from the axis and set visibility to False
    for label in ax.get_xticklabels():
        label.set_visible(False)
    ax.xaxis.offsetText.set_visible(False)

更新:

为了完整起见，mwaskom ( ref to github issue ) 解释了为什么会出现此问题:

So this happens because matplotlib calls axis.reset_ticks() internally when moving the spine. Otherwise, the spine gets moved but the ticks stay in the same place. It's not configurable in matplotlib and, even if it were, I don't know if there is a public API for moving individual ticks. Unfortunately I think you'll have to remove the tick labels yourself after offsetting the spines.
