You can get the chart instance from the event which has the canvas on which you can target the mouse like so:
const options = {
type: 'pie',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
}]
},
options: {
onHover: (evt, activeEls) => {
activeEls.length > 0 ? evt.chart.canvas.style.cursor = 'pointer' : evt.chart.canvas.style.cursor = 'default';
}
}
}
const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
<canvas id="chartJSContainer" width="600" height="400"></canvas>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.6.1/chart.js"></script>
</body>

For who is using ChartJS 4 and come across this question without success to to find the element like previous version. From version 3.x, you can access directly to chart
object in onHover
.
options.onClick and options.onHover now receive the chart instance as a 3rd argument
To change the cursor to pointer, you can do like below:
onHover: (event: ChartEvent, chartElement: ActiveElement[], chart) => {
chartElement.length > 0 ? chart.canvas.style.cursor = 'pointer' : chart.canvas.style.cursor = 'default';
},
it should do the trick
