Report Chart | Lightning Component

Report Chart | Lightning Component | Chart JS

Arun Kumar has shared a blog post about a lighting component that utilizes the Chart.js library to create dynamical, user-customizable charts. Available as an open-source tool, Chart.js offers eight chart types and excels in rendering performance. Kumar also offers an installable package for Salesforce instances.

In this blog post, I am going to share a lighting component that will display a chart based on the selected report and chart type. In this component, I have used the Chart.JS open-source javascript library to draw a chart in the lightning component. The user can select the report and chart type to draw/display the chart and the selection of report name and chart type will be remembered for the user.

Chart JS is a javascript library that allows us to design and draw the different kinds of charts using the HTML 5 canvas element. We can use this library to draw a simple, clean and animated chart. Below are some advantages of using this library for drawing charts.

It is an open-source.
We can use 8 chart types to display the chart.
HTML5 canvas (great rendring performance across all the modern browser)
It is responsive.

	<canvas id="myChart" width="400" height="400"></canvas>
	<script>
	var ctx = document.getElementById('myChart').getContext('2d');
	var myChart = new Chart(ctx, {
	type: 'bar',
	data: {
	labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
	datasets: [{
	label: '# of Votes',
	data: [12, 19, 3, 5, 2, 3],
	backgroundColor: [
	'rgba(255, 99, 132, 0.2)',
	'rgba(54, 162, 235, 0.2)',
	'rgba(255, 206, 86, 0.2)',
	'rgba(75, 192, 192, 0.2)',
	'rgba(153, 102, 255, 0.2)',
	'rgba(255, 159, 64, 0.2)'

	'rgba(153, 102, 255, 1)',
	'rgba(255, 159, 64, 1)'
	],
	borderWidth: 1

	},
	options: {
