vue.jsHow can I use Vue and Chart.js to add zoom functionality to my chart?

To use Vue and Chart.js to add zoom functionality to a chart, you can use the Chart.js zoom plugin. To use it, you must first install it:

$ npm install chartjs-plugin-zoom

Then in your Vue component, you can import the plugin and add it to your chart options:

import Chart from 'chart.js';
import ChartZoom from 'chartjs-plugin-zoom';

export default {
  name: 'MyChart',
  data() {
    return {
      chart: null
    }
  },
  mounted() {
    this.createChart();
  },
  methods: {
    createChart() {
      const ctx = document.getElementById('myChart');
      const myChart = new Chart(ctx, {
        type: 'line',
        data: {
          labels: [],
          datasets: []
        },
        options: {
          plugins: {
            zoom: {
              pan: {
                enabled: true,
                mode: 'xy'
              },
              zoom: {
                enabled: true,
                mode: 'xy'
              }
            }
          }
        }
      });
      this.chart = myChart;
    }
  }
}

This code will add the zoom plugin to the chart, allowing you to pan and zoom the chart. You can find more information about the zoom plugin and its options here.
