Getting Started

This section explains you the steps required to create a simple range navigator and demonstrate the basic usage of the range navigator control.

Dependencies

Below is the list of minimum dependencies required to use the range navigator component.

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

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 range navigator package

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

To install range navigator component, use the following command

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

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

Registering Range Navigator Component

You can register the range navigator component in your application by using the Vue.use().

Refer to the code example given below.

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

Vue.use(RangeNavigatorPlugin);

Registering RangeNavigatorPlugin in vue, will register the range navigator component along with its required child directives globally.

  • Syncfusion ej2-vue-charts packages needs to be mapped in systemjs.config.js configuration file.
/**
 * System configuration for vue samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    transpiler: "typescript",
    typescriptOptions: {

    },
  });
   System.import('index.js');

Adding Range Navigator to the Project

  • Add the Vue Range Navigator by using <ejs-rangenavigator> selector in <template> section of the App.vue file. The below example shows a basic range navigator,
Source
Preview
app.vue
<template>
  <div id="app">
      <ejs-rangenavigator></ejs-rangenavigator>
  </div>
</template>
<script>
import Vue from 'vue';
import { RangeNavigatorPlugin } from '@syncfusion/ej2-vue-charts';

Vue.use(RangeNavigatorPlugin);
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 range navigator with additional features, inject the required modules. The following modules are used to extend rangenavigator’s basic functionality.

•AreaSeries - Inject this module to use area 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 { RangeNavigatorPlugin, AreaSeries, DateTime, RangeTooltip } from "@syncfusion/ej2-vue-charts";

Vue.use(RangeNavigatorPlugin);

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

Populate Range Navigator with Data

Now, we are going to provide data to the range navigator. Add a series object to the range navigator by using series property. Now map the field names x and y in the JSON data to the xName and yName properties of the series, then set the JSON data to dataSource property. Since the JSON contains Datetime data, set the valueType range Navigator to Category. By default, the axis valueType is Numeric.

            <e-rangenavigator-series-collection>
                <e-rangenavigator-series :dataSource='data' type='Area' xName='x' yName='y' width=2>
                </e-rangenavigator-series>
            </e-rangenavigator-series-collection>
        </ejs-rangenavigator>
    </div>
</template>
<script>
import Vue from "vue";
import { RangeNavigatorPlugin, AreaSeries, DateTime } from "@syncfusion/ej2-vue-charts";
import { bitCoinData } from "default_data.ts";

Vue.use(RangeNavigatorPlugin);

export default {
  data() {
    return {
     valueType: 'DateTime',
     value: [new Date('2017-09-01'), new Date('2018-02-01')],
     labelFormat: 'MMM-yy',
     data: bitCoinData
    };
  },
  provide: {
    rangeNavigator: [DateTime, AreaSeries]
  }
};
</script>

Enable Tooltip

The tooltip is useful to show the selected data. You can enable tooltip by setting the enable property as true in tooltip object and by injecting RangeTooltip module using provide method.

     tooltip: { enable: true, displayMode: "Always", format: "MM/dd/yyyy" },
     labelFormat: 'MMM-yy',
     data: bitCoinData
    };
  },
  provide: {
    rangeNavigator: [DateTime, AreaSeries, RangeTooltip]
  }
};
