旋转x轴标签快速网格海运不起作用 [英] Rotate x-axis labels FacetGrid seaborn not working

问题描述

我正在尝试使用python中的seborn创建多面图，但我遇到了很多问题，其中一件事是旋转x轴标签。

我当前正在尝试使用以下代码：

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt 

vin = pd.Series(["W1","W1","W2","W2","W1","W3","W4"])
word1 = pd.Series(['pdi','pdi','tread','adjust','fill','pdi','fill'])
word2 = pd.Series(['perform','perform','fill','measure','tire','check','tire'])
date = pd.Series(["01-07-2020","01-07-2020","01-07-2020","01-07-2020","01-08-2020","01-08-2020","01-08-2020"])

bigram_with_dates = pd.concat([vin,word1,word2,date], axis = 1)
names = ["vin", "word1","word2","date"]
bigram_with_dates.columns = names
bigram_with_dates['date'] = pd.to_datetime(bigram_with_dates['date'])
bigram_with_dates['text_concat'] = bigram_with_dates['word1'] + "," + bigram_with_dates['word2']

plot_params = sns.FacetGrid(bigram_with_dates, col="date", height=3, aspect=.5, col_wrap = 10,sharex = False, sharey = False)
plot = plot_params.map(sns.countplot, 'text_concat', color = 'c', order = bigram_with_dates['text_concat'])
plot_adjust = plot.fig.subplots_adjust(wspace=0.5, hspace=0.5)

for axes in plot.axes.flat:
    axes.set_xticklabels(axes.get_xticklabels(), rotation=90)

当我使用此命令时，我收到一条错误消息，指出：

AttributeError: 'NoneType' object has no attribute 'axes'

，我想我理解它的意思是没有返回的对象，所以在Nothing上设置轴不起任何作用。

这段代码似乎可以在我遇到的其他SO帖子中工作，但是我似乎无法让它工作。

如有任何关于我做错了什么的建议，我将不胜感激。

谢谢， 柯蒂斯

推荐答案

尝试此操作，您似乎覆盖了‘Plot’变量。：

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt 
%matplotlib inline

vin = pd.Series(["W1","W1","W2","W2","W1","W3","W4"])
word1 = pd.Series(['pdi','pdi','tread','adjust','fill','pdi','fill'])
word2 = pd.Series(['perform','perform','fill','measure','tire','check','tire'])
date = pd.Series(["01-07-2020","01-07-2020","01-07-2020","01-07-2020","01-08-2020","01-08-2020","01-08-2020"])

bigram_with_dates = pd.concat([vin,word1,word2,date], axis = 1)
names = ["vin", "word1","word2","date"]
bigram_with_dates.columns = names
bigram_with_dates['date'] = pd.to_datetime(bigram_with_dates['date']).dt.strftime('%m-%d-%Y')
bigram_with_dates['text_concat'] = bigram_with_dates['word1'] + "," + bigram_with_dates['word2']

plot = sns.FacetGrid(bigram_with_dates, col="date", height=3, aspect=.5, col_wrap = 10,sharex = False, sharey = False)
plot1 = plot.map(sns.countplot, 
                 'text_concat', 
                 color = 'c', 
                 order = bigram_with_dates['text_concat'].value_counts(ascending = False).iloc[:5].index)
            .fig.subplots_adjust(wspace=0.5, hspace=12)

for axes in plot.axes.flat:
    _ = axes.set_xticklabels(axes.get_xticklabels(), rotation=90)
plt.tight_layout()
