apexcharts/vue3-apexcharts: 📊 Vue-3 component for ApexCharts

Vue 3 component for ApexCharts to build interactive visualizations in vue.

npm install --save apexcharts
npm install --save vue3-apexcharts

If you're looking for Vue 2.x.x compatibile component, check-out vue-apexcharts

import VueApexCharts from "vue3-apexcharts";

const app = createApp(App);
app.use(VueApexCharts);
// The app.use(VueApexCharts) will make <apexchart> component available everywhere.

OR

// you can import in a particular component and register the component like below
import VueApexCharts from "vue3-apexcharts";
export default {
  components: {
    apexchart: VueApexCharts,
  },
};

To provide a $apexcharts reference inside Vue instance

import ApexCharts from "apexcharts";

app.config.globalProperties.$apexcharts = ApexCharts;

// Add this when into a TypeScript codebase
declare module "@vue/runtime-core" {
  interface ComponentCustomProperties {
    $apexcharts: typeof ApexCharts;
  }
}

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

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']
        }
    }
}}

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.

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

Example

window.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.

Basic Examples are included to show how to get started using ApexCharts with Vue 3 easily.

To run the examples,

cd demo
