Chart.js also provides us a facility to create charts having combination of two or different chart types. Such charts are called mixed charts. One of the most common examples of chart.js mixed chart is a bar chart including a line dataset.
Syntax
The syntax for creating a mixed chart is given below −
type: ''scatter'',
datasets: [
{ type: ''scatter'', data: value, },
{ type: ''bar'', data: value, },
]
Example
Let’s take an example with the help of which we will create a mixed chart −
<!DOCTYPE>
<html>
<head>
<meta charset- "UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>chart.js</title>
</head>
<body>
<canvas id="chartId" aria-label="chart" height="300" width="580"></canvas>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.1.1/chart.min.js"></script>
<script>
var chrt = document.getElementById("chartId").getContext("2d");
var chartId = new Chart(chrt, {
type: ''scatter'',
data: {
labels: ["HTML", "CSS", "JAVASCRIPT", "CHART.JS", "JQUERY", "BOOTSTRP"],
datasets: [{
type: ''scatter'',
label: "online tutorial subjects",
data: [
{x:10, y:14},
{x:25, y:35},
{x:21, y:20},
{x:35, y:28},
{x:15, y:10},
{x:19, y:30}
],
backgroundColor: [''yellow'', ''aqua'', ''pink'', ''lightgreen'', ''gold'', ''lightblue''],
borderColor: [''black''],
radius: 8,
},
{
type: ''polarArea'',
label: "online tutorial exam",
data: [20, 40, 30, 35, 30, 20],
backgroundColor: [''navy'', ''aqua'', ''pink'', ''lightgreen'', ''lightblue'', ''gold''],
borderColor: [''black''],
borderWidth: 2,
pointRadius: 5,
}
],
},
options: {
responsive: false,
scales: {
y: {
beginAtZero: true
}
}
},
});
