我想用 hvplot “区域绘图”一个简单的数据框（比如这里：https://hvplot.pyviz.org/user_guide/Plotting.html），但代码不起作用。由于我是 hvplot 新手，我不太会收到错误消息
将数据框绘制为“条形图”
df.hvplot.bar(x='col2', y=['col1', 'col3'])
有点工作。但传说并不重要。与面积图一样不起作用。
import pandas as pd
import panel as pn
import hvplot.pandas
import matplotlib.pyplot as plt
d = {'col1': [1, 2,3,4,5], 'col2': ['a','b', 'c', 'd', 'e'], 'col3': [11,12,13,14,15]}
df = pd.DataFrame(data=d)
df.hvplot.area(x='col2', y=['col1', 'col3'])
运行我的代码会给出以下错误消息：
