Rotate tick labels for seaborn barplot
提问by Laurennmc
I am trying to display a chart with rotated x-axis labels, but the chart is not displaying.
我正在尝试显示带有旋转 x 轴标签的图表，但该图表未显示。
import seaborn as sns
%matplotlib inline
yellow='#FFB11E'
by_school=sns.barplot(x ='Organization Name',y ='Score',data = combined.sort('Organization Name'),color=yellow,ci=None)
At this point I can see the image, but after I set the xticklabel, I don't see the image anymore only an object reference. (I would post the image, but I don't enough reputation :()
此时我可以看到图像，但是在设置 xticklabel 后，我不再看到图像，只有对象引用。（我会发布图片，但我没有足够的声誉:()
by_school.set_xticklabels('Organization Name',rotation=45)
<matplotlib.axes._subplots.AxesSubplot at 0x3971a6a0>
A similar question is posted here: Rotate label text in seaborn factorplotbut the solution is not working.
这里发布了一个类似的问题：Rotate label text in seaborn factorplot但解决方案不起作用。

You need a different method call, namely .set_rotationfor each ticklables.
Since you already have the ticklabels, just change their rotations:
您需要一个不同的方法调用，即.set_rotation每个ticklables。由于您已经有了刻度标签，只需更改它们的旋转：
for item in by_school.get_xticklabels():
item.set_rotation(45)
barplotreturns a matplotlib.axesobject (as of seaborn0.6.0), therefore you have to rotate the labels this way. In other cases, when the method returns a FacetGridobject, refer to Rotate label text in seaborn factorplot
barplot返回一个matplotlib.axes对象（从seaborn0.6.0 开始），因此您必须以这种方式旋转标签。其他情况，当方法返回FacetGrid对象时，参考在seaborn factorplot中旋转标签文本

If you come here to rotate the labels for a seaborn.heatmap, the following should work (based on @Aman's answerat Rotate label text in seaborn factorplot)
如果您来这里旋转 a 的标签seaborn.heatmap，则以下内容应该有效（基于@Aman 在 Seaborn factorplot中旋转标签文本的回答）
pandas_frame = pd.DataFrame(data, index=names, columns=names)
heatmap = seaborn.heatmap(pandas_frame)
loc, labels = plt.xticks()
heatmap.set_xticklabels(labels, rotation=45)
heatmap.set_yticklabels(labels[::-1], rotation=45) # reversed order for y

Use the following code statement:
使用以下代码语句：
by_school.set_xticklabels(by_school.get_xticklabels(), rotation=90, horizontalalignment='right')

This worked for me:
这对我有用：
g.fig.autofmt_xdate()
回答by wordsforthewise
You can rotate seaborn xticks like so:
你可以像这样旋转seaborn xticks：
sns.barplot(x='Organization Name', y='Score', data=df)
plt.xticks(rotation=70)
plt.tight_layout()
