我有一个与此类似的数据框

import pandas as pd
df = pd.DataFrame([['1','3','1','2','3','1','2','2','1','1'], ['ONE','TWO','ONE','ONE','ONE','TWO','ONE','TWO','ONE','THREE']]).T
df.columns = [['age','data']]
print(df)   #printing dataframe.

我对它执行了groupby函数以获得所需的输出.

df['COUNTER'] =1       #initially, set that counter to 1.
group_data = df.groupby(['age','data'])['COUNTER'].sum() #sum function
print(group_data)

现在我想用matplot lib绘制出来.请帮帮我..我无法想象如何开始和做什么.我想使用计数器值和类似于条形图的东西进行绘图
