You need to set explodeOnClick to false to disable exploding of sections in CanvasJS funnel / pyramid chart. Setting interactivityEnabled property to false, as mentioned by user14299292 will remove complete interactivity of chart - doesn't show toolTip aswell. Below is an example.
var chart = new CanvasJS.Chart("chartContainer", {
data: [{
type: "pyramid",
explodeOnClick: false, //**Change it to true
dataPoints: [
{ y: 10, indexLabel:"Research & Design" },
{ y: 12, indexLabel:"Manufacturing" },
{ y: 8, indexLabel:"Marketing" },
{ y: 8, indexLabel: "Shipping" },
{ y: 15, indexLabel:"Retail" }
]
}]
});
chart.render();
<script src="https://canvasjs.com/assets/script/canvasjs.min.js"></script>
<div id="chartContainer" style="height: 300px; width: 100%;"></div>
