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

    Download and Installation

    Installing via npm
    npm install --save apexcharts
    npm install --save vue-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.
