用Pyecharts绘制dataframe的三列数据对应三个柱形的柱状图，每个柱形旁边显示所占三个柱形的百分比

好的，可以参考如下代码实现：

import pandas as pd
from pyecharts.charts import Bar, Grid, Line
from pyecharts import options as opts
from pyecharts.globals import ThemeType

# 生成数据
data = {
    'A': [10, 20, 30, 40, 50],
    'B': [5, 15, 25, 35, 45],
    'C': [15, 25, 35, 45, 55]
}
df = pd.DataFrame(data)

# 计算每列数据的总和
col_sum = df.sum()

# 计算每个数据所占的百分比
percent = df.apply(lambda x: x/col_sum, axis=1)

# 绘制柱状图
bar = (
    Bar(init_opts=opts.InitOpts(theme=ThemeType.LIGHT))
    .add_xaxis(df.index.tolist())
    .add_yaxis('A', df['A'].tolist())
    .add_yaxis('B', df['B'].tolist())
    .add_yaxis('C', df['C'].tolist())
    .set_global_opts(
        xaxis_opts=opts.AxisOpts(axislabel_opts=opts.LabelOpts(rotate=45)),
        title_opts=opts.TitleOpts(title='柱状图')
    )
)

# 添加百分比标签
for i in range(len(df)):
    bar.add_yaxis(
        series_name='',
        yaxis_data=[],
        label_opts=opts.LabelOpts(
            formatter=opts.FuncFormatter(lambda x: f'{x*100:.2f}%'),
            position='right'
        ),
        itemstyle_opts=opts.ItemStyleOpts(
            color='rgba(0,0,0,0)'
        ),
        markline_opts=opts.MarkLineOpts(
            data=[
                opts.MarkLineItem(
                    y=percent.iloc[i]['A'],
                    name='A',
                    label_opts=opts.LabelOpts(
                        formatter=opts.FuncFormatter(lambda x: f'{x*100:.2f}%'),
                        position='insideRight'
                    )
                ),
                opts.MarkLineItem(
                    y=percent.iloc[i]['B'],
                    name='B',
                    label_opts=opts.LabelOpts(
                        formatter=opts.FuncFormatter(lambda x: f'{x*100:.2f}%'),
                        position='insideRight'
                    )
                ),
                opts.MarkLineItem(
                    y=percent.iloc[i]['C'],
                    name='C',
                    label_opts=opts.LabelOpts(
                        formatter=opts.FuncFormatter(lambda x: f'{x*100:.2f}%'),
                        position='insideRight'
                    )
                )
            ]
        )
    )

# 将柱状图和百分比标签合并为一个图表
grid = (
    Grid(init_opts=opts.InitOpts(theme=ThemeType.LIGHT))
    .add(bar, grid_opts=opts.GridOpts(pos_left='5%', pos_right='5%', pos_bottom='15%'))
)

grid.render_notebook()

这段代码会生成一个柱状图，并在每个柱形旁边显示该柱形所占三个柱形的百分比。你可以将数据替换成自己的数据，并对其他参数进行调整。
