Implementation of funnel and radar chart functions for Vue statistical charts

Implementation of the funnel and radar chart functions of Vue statistical charts

Introduction:
With the increasing demand for data visualization, statistical charts have become an important part of front-end development One of the important components. This article will introduce how to use the Vue framework to implement two common statistical charts, namely funnel charts and radar charts. The code examples will show in detail how to use Vue and the corresponding chart library to implement these two charts.

1. Implementation of the funnel chart function
The funnel chart can be used to display the data flow between multiple links, and is usually used to analyze conversion rates or funnel models. The following will introduce how to use Vue and echarts library to implement a funnel chart.

First, introduce the echarts library into the Vue component, and initialize the echarts instance after the page rendering is completed:

<template>
  <div>
    <div id="funnelChart"></div>
  </div>
</template>

<script>
import echarts from 'echarts'

export default {
  mounted () {
    this.drawFunnelChart()
  },
  methods: {
    drawFunnelChart () {
      const chart = echarts.init(document.getElementById('funnelChart'))
      // ... 设置漏斗图的数据及其他配置
      chart.setOption(option)
    }
  }
}
</script>

Next, you need to design the configuration items of the funnel chart based on the data and draw the corresponding Data:

methods: {
  drawFunnelChart () {
    const chart = echarts.init(document.getElementById('funnelChart'))
    const option = {
      title: {
        text: '漏斗图',
      },
      tooltip: {
        trigger: 'item',
        formatter: '{a} <br/>{b} : {c}'
      },
      legend: {
        data: ['步骤一', '步骤二', '步骤三']
      },
      calculable: true,
      series: [
        {
          name: '漏斗图',
          type: 'funnel',
          left: '10%',
          top: 60,
          bottom: 60,
          width: '80%',
          min: 0,
          max: 100,
          minSize: '0%',
          maxSize: '100%',
          sort: 'descending',
          gap: 2,
          label: {
            show: true,
            position: 'inside'
          },
          labelLine: {
            length: 10,
            lineStyle: {
              width: 1,
              type: 'solid'
            }
          },
          itemStyle: {
            borderColor: '#fff',
            borderWidth: 1
          },
          emphasis: {
            label: {
              fontSize: 20
            }
          },
          data: [
            {value: 60, name: '步骤一'},
            {value: 40, name: '步骤二'},
            {value: 20, name: '步骤三'}
          ]
        }
      ]
    }
    chart.setOption(option)
  }
}

In the above code, we set the title, prompt box, legend and specific data items of the funnel chart. By adjusting the parameters of each configuration item, we can customize it according to actual needs.

2. Radar Chart Function Implementation
Radar chart can be used to display the relative size and trend between multiple indicators. The following will introduce how to use Vue and echarts libraries to implement radar charts.

First, introduce the echarts library into the Vue component, and initialize the echarts instance after the page rendering is completed:

<template>
  <div>
    <div id="radarChart"></div>
  </div>
</template>

<script>
import echarts from 'echarts'

export default {
  mounted () {
    this.drawRadarChart()
  },
  methods: {
    drawRadarChart () {
      const chart = echarts.init(document.getElementById('radarChart'))
      // ... 设置雷达图的数据及其他配置
      chart.setOption(option)
    }
  }
}
</script>

Next, you need to design the configuration items of the radar chart based on the data and draw the corresponding Data:

methods: {
  drawRadarChart () {
    const chart = echarts.init(document.getElementById('radarChart'))
    const option = {
      title: {
        text: '雷达图',
      },
      tooltip: {},
      legend: {
        data: ['预算分配（Allocated Budget）', '实际开销（Actual Spending）']
      },
      radar: {
        indicator: [
          { name: '销售（Sales）', max: 6500},
          { name: '管理（Administration）', max: 16000},
          { name: '信息技术（Information Techology）', max: 30000},
          { name: '客服（Customer Support）', max: 38000},
          { name: '研发（Development）', max: 52000},
          { name: '市场（Marketing）', max: 25000}
        ]
      },
      series: [{
        name: '预算 vs 开销（Budget vs Spending）',
        type: 'radar',
        data : [
          {
            value : [4300, 10000, 28000, 35000, 50000, 19000],
            name : '预算分配（Allocated Budget）'
          },
          {
            value : [5000, 14000, 28000, 31000, 42000, 21000],
            name : '实际开销（Actual Spending）'
          }
        ]
      }]
    }
    chart.setOption(option)
  }
}

In the above code, we set the title, prompt box, legend, radar axis and specific data items of the radar chart. By adjusting the parameters of each configuration item, we can customize it according to actual needs. custom made.

Summary:
This article introduces how to use Vue and the corresponding chart library to implement the functions of funnel charts and radar charts. Through the above code examples, statistical charts can be easily integrated into the Vue project and customized and configured according to actual needs. I hope this article will help you understand the funnel chart and radar chart functions of Vue statistical charts.
