This article provides a step-by-step guide for setting up a Vue 2 project using Vue-CLI and integrating the Syncfusion Vue Circular Gauge component.

Prerequisites

System requirements for Syncfusion Vue UI components

Dependencies

Below is the list of minimum dependencies required to use the Circular Gauge.

|-- @syncfusion/ej2-vue-circulargauge
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-popups
       |-- @syncfusion/ej2-splitbuttons
       |-- @syncfusion/ej2-vue-base
    |-- @syncfusion/ej2-svg-base
    |-- @syncfusion/ej2-circulargauge

Setting up the Vue 2 project

To generate a Vue 2 project using Vue-CLI, use the vue create command. Follow these steps to install Vue CLI and create a new project:

npm install -g @vue/cli
vue create quickstart
cd quickstart
npm run serve

or

yarn global add @vue/cli
vue create quickstart
cd quickstart
yarn run serve

When creating a new project, choose the option Default ([Vue 2] babel, eslint) from the menu.

Once the quickstart project is set up with default settings, proceed to add Syncfusion components to the project.

Add Syncfusion Vue packages

Syncfusion packages are available at npmjs.com. To use Vue components, install the required npm package.

This article uses the Vue Circular gauge component as an example. Install the @syncfusion/ej2-vue-circulargauge package by running the following command:

npm install @syncfusion/ej2-vue-circulargauge --save

or

yarn add @syncfusion/ej2-vue-circulargauge

Adding Syncfusion Vue Circular Gauge component

Follow the below steps to add the Vue Circular Gauge component:

1. First, import and register the Circular Gauge component in the script section of the src/App.vue file.

~/src/App.vue

<script>
import { CircularGaugeComponent } from '@syncfusion/ej2-vue-circulargauge';

export default {
  components: {
    'ejs-circulargauge': CircularGaugeComponent
  }
}
</script>

2. In the template section, define the Circular Gauge component.

~/src/App.vue

<template>
    <div id="app">
      <div class='wrapper'>
         <ejs-circulargauge ></ejs-circulargauge>
      </div>
    </div>
</template>

Here is the summarized code for the above steps in the src/App.vue file:

~/src/App.vue

<template>
    <div id="app">
      <div class='wrapper'>
         <ejs-circulargauge ></ejs-circulargauge>
      </div>
    </div>
</template>
<script>
import { CircularGaugeComponent } from '@syncfusion/ej2-vue-circulargauge';

export default {
  components: {
    'ejs-circulargauge': CircularGaugeComponent
  },
}
</script>
<style>
  .wrapper {
    max-width: 300px;
    margin: 0 auto;
  }
</style>

Run the project

To run the project, use the following command:

npm run serve

or

yarn run serve

Set Pointer Value

You can change the pointer value in the above sample using value property in pointers.

~/src/app.vue

<template>
    <div id="app">
      <div class='wrapper'>
         <ejs-circulargauge >
          <e-axes>
            <e-axis>
              <e-pointers>
                <e-pointer :value='val'/>
              </e-pointers>
            </e-axis>
          </e-axes>
         </ejs-circulargauge>
      </div>
    </div>
</template>
<script>
import { CircularGaugeComponent, AxisDirective, AxesDirective, PointerDirective, PointersDirective } from '@syncfusion/ej2-vue-circulargauge';

export default {
   components: {
    'ejs-circulargauge': CircularGaugeComponent,
    'e-axis': AxisDirective,
    'e-axes': AxesDirective,
    'e-pointer': PointerDirective,
    'e-pointers': PointersDirective
   },
   data () {
    return {
      val : 35
    }
  }
}
</script>
<style>
  .wrapper {
    max-width: 300px;
    margin: 0 auto;
  }
</style>
