Vue HeatMap Component

The Vue Heat Map component is a graphical representation of two-dimensional data where the values are represented with gradient or solid color variations. The data points are rendered as HeatMap cells using Scalable Vector Graphics (SVG) or canvas UI rendering.

Setup

Create a Vue Application

You can use Vue CLI to setup your Vue 2 applications. To install Vue CLI, use the following command.

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

Initiating a new project prompts us to choose the type of project to be used for the current application. Select the option Default ([Vue 2] babel, eslint) from the menu.

Add Syncfusion HeatMap package

All Syncfusion Vue packages are published in npmjs.com registry. To install Vue Heat Map package, use the following command.

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

Register HeatMap Component

You can register the HeatMap component in your application by using the Vue.use(). Refer to the code example given below.

import { HeatMapPlugin } from '@syncfusion/ej2-vue-heatmap';

Vue.use(HeatMapPlugin);

Registering HeatMapPlugin in Vue, will register the HeatMap component along with its required child directives globally.

Add HeatMap Component

Add the Vue HeatMap by using ejs-heatmap selector in template section of the App.vue file.

<template>
    <div id="app">
        <ejs-heatmap :dataSource='dataSource'></ejs-heatmap>
    </div>
</template>
<script>
import Vue from 'vue';
import { HeatMapPlugin } from '@syncfusion/ej2-vue-heatmap';

Vue.use(HeatMapPlugin);
export default Vue.extend ({
  data: function() {
    return {
	    dataSource: [
            [73, 39, 26, 39, 94, 0],
            [93, 58, 53, 38, 26, 68],
            [99, 28, 22, 4, 66, 90],
            [14, 26, 97, 69, 69, 3],
            [7, 46, 47, 47, 88, 6],
            [41, 55, 73, 23, 3, 79],
            [56, 69, 21, 86, 3, 33],
            [45, 7, 53, 81, 95, 79],
            [60, 77, 74, 68, 88, 51],
            [25, 25, 10, 12, 78, 14],
