Optimization of 3D stereoscopic and rotation effects for Vue statistical charts

Optimization of 3D stereoscopic and rotation effects of Vue statistical charts

In the field of data visualization, statistical charts are one of the most important tools, which can transform complex data It is a visual form that makes it easier for people to understand and analyze data. In the Vue framework, we can realize the display and operation of statistical charts by introducing some excellent plug-ins.

This article will take a histogram as an example to introduce how to use the echarts plug-in in Vue to optimize the 3D stereoscopic and rotation effects of statistical charts. First, we need to install the echarts plug-in, which can be installed through npm or yarn:

npm install echarts --save

After the installation is complete, we can introduce echarts into the Vue component and use it to create histograms. Here is a simple example:

<template>
  <div class="chart-container">
    <div ref="chart" class="chart"></div>
  </div>
</template>

<script>
import echarts from 'echarts';

export default {
  mounted() {
    this.initChart();
  },
  methods: {
    initChart() {
      const chartDom = this.$refs.chart;
      const myChart = echarts.init(chartDom);

      const option = {
        tooltip: {
          trigger: 'axis',
          axisPointer: {
            type: 'shadow',
          },
        },
        grid: {
          top: '10%',
          left: '3%',
          right: '4%',
          bottom: '3%',
          containLabel: true,
        },
        xAxis: {
          type: 'category',
          data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
          axisLine: {
            show: true,
          },
        },
        yAxis: {
          type: 'value',
          axisLine: {
            show: true,
          },
        },
        series: [
          {
            type: 'bar',
            data: [120, 200, 150, 80, 70, 110, 130],
            itemStyle: {
              color: '#69c0ff',
            },
          },
        ],
      };

      myChart.setOption(option);
      this.chart = myChart;
    },
  },
};
</script>

<style scoped>
.chart-container {
  width: 100%;
  height: 400px;
}

.chart {
  width: 100%;
  height: 100%;
}
</style>

In the above code, we create a Vue component named Chart, initialize the chart in the component's mounted lifecycle hook function, and pass the component's refs The attribute obtains the DOM element, and then uses the echarts.init method to initialize an echarts instance. Subsequently, we defined an option object to configure various parameters of the chart, including icon type, data, coordinate axes, etc.

In the above example, we can also set the color of the histogram by configuring itemStyle. You can configure other styles and parameters according to your own needs. In the myChart.setOption method, we pass in the previously defined option object as a parameter to apply the configuration.

So far, we have implemented a simple histogram display. However, in order to further optimize the user experience, we can add some 3D stereoscopic and rotation effects to the chart. The following is a code example:

initChart() {
  const chartDom = this.$refs.chart;
  const myChart = echarts.init(chartDom, null, {
    renderer: 'svg',
  });

  const option = {
    tooltip: {
      trigger: 'axis',
      axisPointer: {
        type: 'shadow',
      },
    },
    grid3D: {
      boxWidth: 150,
      boxDepth: 80,
      viewControl: {
        // 3D旋转
        orbitRotation: 45,
      },
    },
    xAxis3D: {
      type: 'category',
      data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
      axisLine: {
        show: true,
      },
    },
    yAxis3D: {
      type: 'value',
      axisLine: {
        show: true,
      },
    },
    zAxis3D: {
      type: 'value',
      axisLine: {
        show: true,
      },
    },
    series: [
      {
        type: 'bar3D',
        data: [
          ['Mon', 0, 120],
          ['Tue', 1, 200],
          ['Wed', 2, 150],
          ['Thu', 3, 80],
          ['Fri', 4, 70],
          ['Sat', 5, 110],
          ['Sun', 6, 130],
        ],
        shading: 'color',
        label: {
          show: true,
          textStyle: {
            color: '#000',
            fontSize: 12,
          },
        },
        emphasis: {},
      },
    ],
  };

  myChart.setOption(option);
  this.chart = myChart;
}

In the above code, we first modified the third parameter of the echarts.init method and set the renderer to 'svg' to enable the 3D function. Then, new parameters such as grid3D, xAxis3D, yAxis3D and zAxis3D were added to the option object to configure various parameters of the 3D effect.

In the series parameters, we set the chart type to bar3D and pass in the corresponding data through data. Each data includes category, x coordinate and y coordinate. By adding configuration items to the corresponding parameters in the option object, we can achieve the 3D stereoscopic and rotation effects of the histogram.

Through the above code examples, we can easily display the chart in the Vue project and optimize the 3D stereoscopic and rotation effects of the chart. Of course, echarts also provides rich API and configuration options to meet more complex needs. I hope this article will help you optimize the 3D effect of statistical charts in Vue.
