Usage

import VueApexCharts from "vue3-apexcharts";

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

OR

// you can import in a particular component and register the component like below
import VueApexCharts from "vue3-apexcharts";

    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>
    
  </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">
    
    <div>
      <button>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

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.

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 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.
