[英]How to prevent pandas.Dataframe.hist() from creating subplots with superimposed data?
[英]Save pandas.DataFrame.hist with multiple axes in one figure
我有一个包含24列的pandas数据pandas.DataFrame.hist
,并且使用函数pandas.DataFrame.hist
生成带有一些子图的图形。
plot = df.hist(figsize = (20, 15))
plot
array([[<matplotlib.axes._subplots.AxesSubplot object at 0x0000000018D47EB8>,

问题是,当我尝试将此图形保存到单个PNG文件中时,出现错误
plot.savefig(os.path.join(folder_wd, folder_output, folder_dataset,'histogram.png'))
AttributeError:“ numpy.ndarray”对象没有属性“ savefig”
到目前为止,我所检查的文章均未提供解决方案
savefig
不是的方法plot
由返回的对象df.hist
。 尝试以下
import matplotlib.pyplot as plt
# rest of your code
plot = df.hist(figsize = (20, 15))
plt.savefig(os.path.join(folder_wd, folder_output, folder_dataset,'histogram.png'))
