我想使用hvplot对区域进行简单的数据框绘制（例如：https://hvplot.pyviz.org/user_guide/Plotting.html），但是代码无法正常工作。由于我是hvplot的新手，所以我不太了解错误消息

将数据框绘制为“条形图”

df.hvplot.bar(x='col2',y=['col1','col3'])

kinda有用。但是传说并没有到位。与区域图相同无法正常工作。

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','col3'])

运行我的代码会显示以下错误消息：
