Plotly.js 创建堆叠和分组条形图 [英] Plotly.js Create stacked and grouped bar chart

问题描述

如何在 Plotly.js 上使用分组和堆叠条形图创建条形图?我需要这样的结构:

 Plotly.newPlot("我的分区",[{x: ["A", "B", "C"],y: [0.3, 0.35, 0.4],类型:酒吧"，名称:系列1a"，xaxis: 'x1',barmode: '堆栈',标记:{颜色:'#448'}},{x: ["A", "B", "C"],y: [0.6, 0.50, 0.40],类型:酒吧"，名称:系列1b"，xaxis: 'x1',条形模式:'堆栈'，标记:{颜色:'#88C'}},{x: ["A", "B", "C"],y: [0.1, 0.15, 0.20],类型:酒吧"，名称:系列1c"，xaxis: 'x1',barmode: '堆栈',标记:{颜色:'#CCF'}},{x: ["A", "B", "C"],y: [0.3, 0.35, 0.4],类型:酒吧"，名称:系列2a"，xaxis: 'x2',条形模式:'堆栈'，标记:{颜色:'#080'}},{x: ["A", "B", "C"],y: [0.25, 0.15, 0.05],类型:酒吧"，名称:系列2b"，xaxis: 'x2',barmode: 'stack', 标记: {color: '#8c8'}},{x: ["A", "B", "C"],y: [0.45, 0.50, 0.55],类型:酒吧"，名称:系列2c"，xaxis: 'x2',barmode: 'stack', 标记: {color: '#CFC'}},{x: ["A", "B", "C"],y: [0.3, 0.35, 0.4],类型:酒吧"，名称:系列3a"，xaxis: 'x3',barmode: 'stack', 标记: {color: '#880'}},{x: ["A", "B", "C"],y: [0.6, 0.50, 0.40],类型:酒吧"，名称:系列3b"，xaxis: 'x3',barmode:'堆栈'，标记:{颜色:'#CC8'}},{x: ["A", "B", "C"],y: [0.1, 0.15, 0.20],类型:酒吧"，名称:3c系列"，xaxis: 'x3',条形模式:'堆栈'，标记:{颜色:'#FFC'}},],{条形模式:堆栈"，yaxis: {tickformat: '%'},x轴:{域:[0, 0.33],锚点:'x1'，书名:《苹果》},xaxis2:{域:[0.33, 0.66]，锚点:'x2'，标题:'梨'},xaxis3:{域:[0.67, 1.0]，锚点:'x3'，标题:'樱桃'}});

How to create barchart on Plotly.js with grouped and stacked bars? I need structure like that: Barchart with stacked and grouped charts

解决方案

It is possible to create a grouped-and-stacked bar chart in Plotly.js by creating each group as a subplot. It's not as simple as setting a top-level feature like 'barmode': 'stacked+grouped' but because it's more elemental it offers more options.

See https://community.plot.ly/t/combination-of-grouped-and-stacked-bar-chart/2154

Here each subplot references a shared common yaxis and its own xaxis. Each xaxis gets a "domain" which here means a portion of the overall bottom axis width. Here the first group gets [0.0, 0.33], the second [0.34, 0.66] and the third [0.67, 1.0]

   Plotly.newPlot(
  "myDiv",
  [
    {
      x: ["A", "B", "C"],
      y: [0.3, 0.35, 0.4],
      type: "bar",
      name: "series 1a", 
      xaxis: 'x1',
      barmode: 'stack', 
      marker: {color: '#448'}
    },
    {
      x: ["A", "B", "C"],
      y: [0.6, 0.50, 0.40],
      type: "bar",

    yaxis: {tickformat: '%'},
    xaxis: {
      domain: [0, 0.33],
      anchor: 'x1',
