"Line2D"对象没有属性“种类" [英] 'Line2D' object has no property 'kind'

问题描述

我刚刚开始学习熊猫，当时我想绘制2013年车站平均值的条形图，以创建 fig，ax = plt.subplots()对象并添加绘制到所创建的斧头'，我在运行代码"Line2D"对象的这一部分时遇到此错误，没有属性种类"

I just started learning pandas, when I wanted to make a bar plot of the mean of the stations in year of 2013 on creating a fig, ax = plt.subplots() object and adding the plot to the created ax' I am getting this error while running this part of the code 'Line2D' object has no property 'kind'

fig,ax = plt.subplots(1)
x= data.columns
y=data['2013'].mean()
ax.plot(x,y,kind='bar')
```````````````````````

另一方面，我尝试使用此代码选择不同年份的4月，5月和6月的所有数据

on the other hand I try to select all data in April, May and June for all different years with this code

data[(data.index.month == 4) & (data.index.month == 5) & (data.index.month == 6)]

我也尝试过这种方式

data.loc[(data.index.month == 4) & (data.index.month == 5) & (data.index.month == 6)]

它什么也没显示，只是空列显示.

it shows me nothing, just a display of empty columns.

推荐答案

对于第一个问题，您必须使用 data.plot(x，y，kind ='bar')，而不是 ax.plot().

For your first question, you have to use data.plot(x, y, kind='bar'), not ax.plot().

fig,ax = plt.subplots(1)
ax = data['2013'].mean().plot(kind='bar')
ax.set_xlabel('x label name')   # replace with the labels you want
ax.set_ylabel('Mean')
plt.xticks(rotation=30)
plt.show()

第二个问题-使用 data [data.index.month.isin([4,5,6])]
