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)'
],
borderColor: [
'rgba(255, 99, 132, 1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
}
}
});
</script>
I have created a package that you can install in your salesforce instance.
