Vue.js wrapper for ApexCharts to build interactive visualizations in vue.

Download and Installation

Installing via npm

npm install vue-apexcharts apexcharts

Usage

import VueApexCharts from 'vue-apexcharts'

Vue.use(VueApexCharts)

To create a basic bar chart with minimal configuration, write as follows:

<template>
   <div>
     <apexcharts width="500" type="bar" :options="chartOptions" :series="series"></apexcharts>
   </div>
</template>

import VueApexCharts from 'vue-apexcharts'

export default {
    components: {
      apexcharts: VueApexCharts,
    },
    data: function() {
      return {
        chartOptions: {
          chart: {
            id: 'vuechart-example'
          },
          xaxis: {
            categories: [1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998]
          }
        },
        series: [{
          name: 'series-1',
          data: [30, 40, 45, 50, 49, 60, 70, 91]
        }]
      }
    },
};

This will render the following chart

How do I update the chart?

Simple! Just change the series or any option and it will automatically re-render the chart. Have a look at the below example to see this in action

<template>
   <div class="app">
     <apexcharts width="550" type="bar" :options="chartOptions" :series="series"></apexcharts>
     <div>
       <button @click="updateChart">Update!</button>
    </div>
   </div>

</template>

export default {
    data: function() {
      return {
        chartOptions: {
          chart: {
            id: 'vuechart-example',
          },
          xaxis: {
            categories: [1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998],
          },
        },
        series: [{
          name: 'series-1',
          data: [30, 40, 45, 50, 49, 60, 70, 81]
        }]
      }
    },
    methods: {
      updateChart() {
        const max = 90;
        const min = 20;
        const newData = this.series[0].data.map(() => {
          return Math.floor(Math.random() * (max - min + 1)) + min
        })

        const colors = ['#008FFB', '#00E396', '#FEB019', '#FF4560', '#775DD0']

        // Make sure to update the whole options config and not just a single property to allow the Vue watch catch the change.
        this.chartOptions = {
          colors: [colors[Math.floor(Math.random()*colors.length)]]
        };
        // In the same way, update the series option
        this.series = [{
          data: newData
        }]
      }
    }
};

How to call methods of ApexCharts programatically?

Sometimes, you may want to call other methods of the core ApexCharts library, and you can do so on this.$apexcharts global variable directly

Example

this.$apexcharts.exec('vuechart-example', 'updateSeries', [{
  data: [40, 55, 65, 11, 23, 44, 54, 33]
}])

In the above method, vuechart-example is the ID of chart, updateSeries is the name of the method you want to call and the third parameter is the new Series you want to update.

More info on the .exec() method can be found here

All other methods of ApexCharts can be called the same way.
