## Download and Installation

##### Installing via npm

```bash
npm install --save apexcharts
npm install --save vue3-apexcharts
```

If you're looking for Vue 2.x.x compatibile component, check-out <a href="https://github.com/apexcharts/vue-apexcharts">vue-apexcharts</a>

## Usage

```js
import VueApexCharts from "vue3-apexcharts";

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

OR

```js
// 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

```ts
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:

```vue
<template>
  <div>
    <apexchart
      width="500"
      type="bar"
      :options="chartOptions"
      :series="series"
    ></apexchart>
  </div>
</template>
```

```js
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. <br/> Click on the below example to see this in action

<p><img src="https://apexcharts.com/media/vue-chart-updation.gif"></p>

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

```js
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

```javascript
this.chartOptions = {
  ...this.chartOptions,
  ...{
    xaxis: {
      labels: {
        style: {
          colors: ["red"],
        },
      },
    },
  },
};
```

❌ Not this

```javascript
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.

| Method                                                                                   | Description                                                                                        |

## 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 <code>chart.id</code> while calling this method

Example

```js
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 <a href="https://apexcharts.com/docs/methods/#exec">here</a>

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