Plotly-express-23-绘制水平柱状图

本文中介绍的是如何利用Plotly_express绘制水平方向的柱状图

• 单组水平柱状图
• 多组水平柱状图

单组水平柱状图

效果

代码

import plotly as py
import plotly.graph_objs as go

data = [go.Bar(
            x=[21, 38, 30],
            y=['小明', '小红', '小军'],
            orientation = 'h'   # 改成h
)]
layout = go.Layout(
            title = '年龄'
    )
fig = go.Figure(data = data, layout = layout)

fig.show()
