Download and Installation

Installing via npm

If you're looking for Vue 3.x.x compatibile component, check-out vue3-apexcharts

Usage

import VueApexCharts from 'vue-apexcharts'
Vue.use(VueApexCharts)

Vue.component('apexchart', VueApexCharts)

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

<template>
   <div>
     <apexchart width="500" type="bar" :options="chartOptions" :series="series"></apexchart>
   </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, 35, 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.
Click on the below example to see this in action

<template>
   <div class="app">
     <apexchart width="550" type="bar" :options="chartOptions" :series="series"></apexchart>
     <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
        }]
      }
    }
};

Important: While updating the options, make sure to update the outermost property even when you need to update the nested property.

✅ Do this

this.chartOptions = {...this.chartOptions, ...{
    xaxis: {
        labels: {
           style: {
             colors: ['red']
           }
        }
    }
}}

❌ Not this

this.chartOptions.xaxis = {
    labels: {
        style: {
          colors: ['red']
        }
    }
}}

Props

Prop	Type	Description
series*	Array	The series is an array which accepts an object in the following format. To know more about the format of dataSeries, checkout Series docs on the website.
type*	String	`line`, `area`, `bar`, `pie`, `donut`, `scatter`, `bubble`, `heatmap`, `radialBar`, `candlestick`
width	Number/String	Possible values for width can be `100%` or `400px` or `400`
height	Number/String	Possible values for height can be `100%` or `300px` or `300`
options	Object	The configuration object, see options on API (Reference)

Methods

You don't actually need to call updateSeries() or updateOptions() manually. Changing the props will automatically update the chart. You only need to call these methods to update the chart forcefully.

Method	Description
updateSeries	Allows you to update the series array overriding the existing one
updateOptions	Allows you to update the configuration object
toggleSeries	Allows you to toggle the visibility of series programatically. Useful when you have custom legend.
appendData	Allows you to append new data to the series array.
addText	The addText() method can be used to draw text after chart is rendered.
addXaxisAnnotation	Draw x-axis annotations after chart is rendered.
addYaxisAnnotation	Draw y-axis annotations after chart is rendered.
addPointAnnotation	Draw point (xy) annotations after chart is rendered.

How to call the methods mentioned above?

<template>
  <div class="example">
    <apexchart ref="demoChart" width="500" :options="chartOptions" :series="series"></apexchart>
  </div>
</template>

<script>
  functionName: function() {
    this.$refs.demoChart.updateOptions({ colors: newColors })
  },
</script>

How to call methods of ApexCharts without referencing the chart element?

Sometimes, you may want to call methods of the core ApexCharts library from some other place, and you can do so on this.$apexcharts global variable directly. You need to target the chart by chart.id while calling this method

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.
