二.代码展示

1.stack名称相同(直接堆叠)

2. stack名称不相同(相同的堆叠,不同的新生成一列)


一.如何实现

数据堆叠,同个类目轴上系列配置相同的 stack 值可以堆叠放置。即在series中将设置stack即可。其他设置与普通柱状图相同,参考文章:数据可视化高级技术Echarts(快速上手&柱状图&进阶操作)-CSDN博客

语法:相同名称的数据会堆叠起来,不同则会新生成一列

stack:"名称"

注:目前 stack 只支持堆叠于 'value' 和 'log' 类型的类目轴上,不持 'time' 和 'category' 类型的类目轴。

二.代码展示

1.stack名称相同(直接堆叠)

下面定义了五种数据,分别定义了五个不太的名字来设定,再分别在各个数据下设定stack(名称为total)

option = {
  tooltip: {
    trigger: 'axis',
    axisPointer: {
      // Use axis to trigger tooltip
      type: 'shadow' // 'shadow' as default; can also be 'line' or 'shadow'
    }
  },
  legend: {},
  grid: {
    left: '3%',
    right: '4%',
    bottom: '3%',
    containLabel: true
  },
  xAxis: {
    type: 'value'
  },
  yAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  series: [
    {
      name: 'Direct',
      type: 'bar',
      stack: 'total',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [320, 302, 301, 334, 390, 330, 320]
    },
    {
      name: 'Mail Ad',
      type: 'bar',
      stack: 'total',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [120, 132, 101, 134, 90, 230, 210]
    },
    {
      name: 'Affiliate Ad',
      type: 'bar',
      stack: 'total',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [220, 182, 191, 234, 290, 330, 310]
    },
    {
      name: 'Video Ad',
      type: 'bar',
      stack: 'total',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [150, 212, 201, 154, 190, 330, 410]
    },
    {
      name: 'Search Engine',
      type: 'bar',
      stack: 'total',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [820, 832, 901, 934, 1290, 1330, 1320]
    }
  ]
};

 

2. stack名称相同(相同的堆叠,不同的新生成一列)

更改为三列,即设置三个不同的stack名称(total,total11,total22)

option = {
  tooltip: {
    trigger: 'axis',
    axisPointer: {
      // Use axis to trigger tooltip
      type: 'shadow' // 'shadow' as default; can also be 'line' or 'shadow'
    }
  },
  legend: {},
  grid: {
    left: '3%',
    right: '4%',
    bottom: '3%',
    containLabel: true
  },
  xAxis: {
    type: 'value'
  },
  yAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  series: [
    {
      name: 'Direct',
      type: 'bar',
      stack: 'total',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [320, 302, 301, 334, 390, 330, 320]
    },
    {
      name: 'Mail Ad',
      type: 'bar',
      stack: 'total',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [120, 132, 101, 134, 90, 230, 210]
    },
    {
      name: 'Affiliate Ad',
      type: 'bar',
      stack: 'total11',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [220, 182, 191, 234, 290, 330, 310]
    },
    {
      name: 'Video Ad',
      type: 'bar',
      stack: 'total11',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [150, 212, 201, 154, 190, 330, 410]
    },
    {
      name: 'Search Engine',
      type: 'bar',
      stack: 'total22',
      label: {
        show: true
      },
      emphasis: {
        focus: 'series'
      },
      data: [820, 832, 901, 934, 1290, 1330, 1320]
    }
  ]
};
