使用数据帧使用Bokeh的水平分组Barplot

import pandas as pd
from bokeh.plotting import figure, show
from bokeh.models import ColumnDataSource
from bokeh.io import output_notebook

data = {'Group': ['A', 'B', 'C'],
        'Value1': [10, 15, 12],
        'Value2': [8, 10, 14]}
df = pd.DataFrame(data)

source = ColumnDataSource(df)

p = figure(x_range=df['Group'], plot_height=350, title='Horizontal Grouped Barplot')

p.vbar(x='Group', top='Value1', width=0.2, source=source, color='blue', legend_label='Value1')
p.vbar(x='Group', top='Value2', width=0.2, source=source, color='red', legend_label='Value2')

p.xgrid.grid_line_color = None
p.legend.location = 'top_right'
p.legend.orientation = 'horizontal'

output_notebook()
show(p)
