|-- @syncfusion/ej2-charts
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-pdf-export
    |-- @syncfusion/ej2-file-utils
    |-- @syncfusion/ej2-compression
    |-- @syncfusion/ej2-svg-base
    |-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-calendars
    |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-lists
    |-- @syncfusion/ej2-inputs

Installation and Configuration

Setup Vue Environment

You can use Vue CLI to setup your vue applications. To install Vue CLI use the following commands.

npm install -g @vue/cli
npm install -g @vue/cli-init

Create a Vue Application

Start a new Vue application using below Vue CLI command.

vue init webpack-simple quickstart

cd quickstart
npm install

Adding Syncfusion Chart package

All the available Essential JS 2 packages are published in npmjs.com registry.

To install chart component, use the following command

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

The —save will instruct NPM to include the chart package inside of the dependencies section of the package.json.

Registering Stock Chart Component

You can register the Stock chart component in your application by using the Vue.use().

Refer to the code example given below.

import { StockChartPlugin } from '@syncfuion/ej2-vue-charts';

Vue.use(StockChartPlugin);

Registering StockChartPlugin in vue, will register the stock chart component along with its required child directives globally.

Adding Stock chart to the Project

  • Add the Vue Stock Chart by using <ejs-stockchart> selector in <template> section of the App.vue file. The below example shows a basic stock chart,
<template>
  <div id="app">
      <ejs-stockchart></ejs-stockchart>
  </div>
</template>
<script>
import Vue from 'vue';
import { StockChartPlugin } from '@syncfusion/ej2-vue-charts';

Vue.use(StockChartPlugin);
export default {
  data () {
    return {
    }
  }
}
</script>

Run the application

The quickstart project is configured to compile and run the application in the browser. Use the following command to run the application.

  • Now run the application in the browser using the below command.
npm run dev

Module Injection

To create stock chart with additional features, inject the required modules. The following modules are used to extend stock chart’s basic functionality.

•CandleSeries - Inject this module to use candle series. •DateTime - Inject this module to use date time axis. •RangeTooltip - Inject this module to show the tooltip.

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

import Vue from "vue";
import { StockChartPlugin, CandleSeries, DateTime, RangeTooltip } from "@syncfusion/ej2-vue-charts";

Vue.use(StockChartPlugin);

export default {
 provide: {
   stockChart: [CandleSeries, DateTime, RangeTooltip]
 }
};
</script>

Populate Stock Chart with Data

This section explains how to plot below JSON data to the Stock Chart. Please find the below imported datasource.

export default {
  data() {
    return {
     data: [{
   x: new Date( '2012-04-02' ),
    open : 85.9757,
    high : 90.6657,
    low : 85.7685,
    close : 90.5257,
    volume : 660187068
  },
  {
   x: new Date( '2012-04-09' ),
    open : 89.4471,
    high : 92,
    low : 86.2157,
    close : 86.4614,
    volume : 912634864
  },
  {
   x: new Date( '2012-04-16' ),
    open : 87.1514,
    high : 88.6071,
    low : 81.4885,
    close : 81.8543,
    volume : 1221746066
  },
  {
   x: new Date( '2012-04-23' ),
    open : 81.5157,
    high : 88.2857,
    low : 79.2857,
    close : 86.1428,
    volume : 965935749
  },
  {
   x: new Date( '2012-04-30' ),
    open : 85.4,
    high : 85.4857,
    low : 80.7385,
    close : 80.75,
    volume : 615249365
  }];
};
}
};

Add a series object to the Stock chart by using series property and then set the JSON data to dataSource property.

Since the JSON contains category data, set the valueType for horizontal axis to Category. By default, the axis valueType is Numeric.

Add Stock Chart Title

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

    ]
  }
};

Add Crosshair

Crosshair has a vertical and horizontal line to view the value of the axis at mouse or touch position.

Crosshair lines can be enabled by using enable property in the crosshair. Likewise tooltip label for an axis can be enabled by using enable property of crosshairTooltip in the corresponding axis.

      BollingerBands, TmaIndicator, MomentumIndicator, SmaIndicator, AtrIndicator,      AccumulationDistributionIndicator,  MacdIndicator, StochasticIndicator, Export
    ]
  }
};
</script>

Add Trackball

Trackball is used to track a data point closest to the mouse or touch position. Trackball marker indicates the closest point and trackball tooltip displays the information about the point. To use trackball feature, we need to inject Crosshair and Tooltip into the provide.

Trackball can be enabled by setting the enable property of the crosshair to true and shared property in tooltip to true in chart.
