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

Prerequisites

System requirements for Syncfusion Vue UI components

Dependencies

Below is the list of minimum dependencies required to use the Bullet Chart component.

|-- @syncfusion/ej2-vue-charts
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-pdf-export
    |-- @syncfusion/ej2-file-utils
    |-- @syncfusion/ej2-compression
    |-- @syncfusion/ej2-charts
    |-- @syncfusion/ej2-vue-base
    |-- @syncfusion/ej2-svg-base

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.

Vue 2 project

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 Bullet chart component as an example. Install the @syncfusion/ej2-vue-charts package by running the following command:

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

or

yarn add @syncfusion/ej2-vue-charts

The –save will instruct NPM to include the Bullet Chart package inside of the dependencies section of the package.json.

Add Syncfusion Vue component

Follow the below steps to add the Vue Bullet chart component using:

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

<script>
import { BulletChartComponent } from '@syncfusion/ej2-vue-charts';

export default {
  components: {
    'ejs-bulletchart': BulletChartComponent
  }
}
</script>

2. In the template section, define the Bullet chart component.

<template>
  <div>
      <ejs-bulletchart id="bulletChart"> </ejs-bulletchart>
  </div>
</template>

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

<template>
  <div>
    <ejs-bulletchart id="bulletChart"> </ejs-bulletchart>
  </div>
</template>
<script>
import { BulletChartComponent } from '@syncfusion/ej2-vue-charts';

export default {
  name: "App",
  components: {
    'ejs-bulletchart': BulletChartComponent
  },
  data() {
    return {
    }
  }
}
</script>

Run the project

To run the project, use the following command:

npm run serve

or

yarn run serve

Module Injection

Bullet Chart component are segregated into individual feature-wise modules. In order to use a particular feature, you need to inject its feature module using provide method. In the current application,we are going to use tooltip feature of the Bullet Chart.

  • BulletTooltip - Inject this provider to use tooltip feature.

These modules should be injected to the provide method as follows,

import { BulletChartComponent, BulletTooltip } from "@syncfusion/ej2-vue-charts";

export default {
  components: {
    'ejs-bulletchart': BulletChartComponent
  },
  provide: {
    bulletChart: [BulletTooltip]
  }
};

BulletChart With Data

This section explains how to plot local data to the Bullet Chart.

let data: any[] = [
       { value: 100, target: 80 },
       { value: 200, target: 180 },
       { value: 300, target: 280 },
       { value: 400, target: 380 },
       { value: 500, target: 480 },
];

Now assign the local data to dataSource property. value and target values should be mapped with valueField and targetField respectively.

<template>
  <div>
    <ejs-bulletchart id="bulletChart" :dataSource="data" valueField="value" targetField="target" height="300"
      :minimum="minimum" :maximum="maximum" :interval="interval"> </ejs-bulletchart>
  </div>
</template>
<script>
import { BulletChartComponent } from '@syncfusion/ej2-vue-charts';

export default {
  name: "App",
  components: {
    'ejs-bulletchart': BulletChartComponent
  },
  data() {
    return {
      data: [
        { value: 100, target: 80 },
        { value: 200, target: 180 },
        { value: 300, target: 280 },
        { value: 400, target: 380 },
        { value: 500, target: 480 },
      ],
      minimum: 0, maximum: 300, interval: 50
    }
  }
}
</script>

Add Bullet Chart Title

You can add a title using title property to the Bullet Chart to provide quick
information to the user about the data plotted in the Bullet Chart.

<template>
  <div>
      <ejs-bulletchart id="bulletChart"
        :dataSource="data"
        valueField="value"
        targetField="target"
        :minimum="minimum"
        :maximum="maximum"
        :interval="interval"
        title="Revenue"
      > </ejs-bulletchart>
  </div>
</template>
<script>
import { BulletChartComponent } from '@syncfusion/ej2-vue-charts';

export default {
name: "App",
  components: {
    'ejs-bulletchart': BulletChartComponent
  },
  data () {
    return {
      data: [{ value: 270, target: 250 }],
      minimum: 0, maximum: 300, interval: 50
    }
  }
}
</script>

Ranges

You can add a range using e-bullet-range of the e-bullet-range-collection.

<template>
  <div>
    <ejs-bulletchart id="bulletChart" :dataSource="data" valueField="value" targetField="target" :minimum="minimum"
      :maximum="maximum" :interval="interval" title="Revenue">
      <e-bullet-range-collection>
        <e-bullet-range end="100" color="red"></e-bullet-range>
        <e-bullet-range end="200" color="blue"></e-bullet-range>
        <e-bullet-range end="300" color="green"></e-bullet-range>
      </e-bullet-range-collection>
    </ejs-bulletchart>
  </div>
</template>
<script>
import { BulletChartComponent, BulletRangeCollectionDirective, BulletRangeDirective } from '@syncfusion/ej2-vue-charts';

export default {
  name: "App",
  components: {
    'ejs-bulletchart': BulletChartComponent,
    'e-bullet-range-collection': BulletRangeCollectionDirective,
    'e-bullet-range': BulletRangeDirective
  },
  data() {
    return {
      data: [{ value: 270, target: 250 }],
      minimum: 0, maximum: 300, interval: 50
    }
  }
}
</script>

Tooltip

You can use tooltip for the Bullet Chart by setting the enable property to true in tooltip object and by injecting the BulletTooltip module using provide method.

<template>
  <div>
    <ejs-bulletchart id="bulletChart" :dataSource="data" valueField="value" targetField="target" :minimum="minimum"
      :maximum="maximum" :interval="interval" title="Revenue" :tooltip="tooltip"> </ejs-bulletchart>
  </div>
</template>
<script>
import { BulletChartComponent, BulletTooltip } from '@syncfusion/ej2-vue-charts';

export default {
  name: "App",
  components: {
    'ejs-bulletchart': BulletChartComponent
  },
  data() {
    return {
      data: [{ value: 270, target: 250 }],
      minimum: 0, maximum: 300, interval: 50,
      tooltip: { enable: true }
    }
  },
  provide: {
    bulletChart: [BulletTooltip]
  }
}
</script>
