How to clear a chart from a canvas so that hover events cannot be triggered?

Question

I\'m using Chartjs to display a Line Chart and this works fine:

// get line chart canvas
var targetCanvas = document.getElementById(\'chartCanvas\').getConte         


        

Answer 1

For me this worked:

		var in_canvas = document.getElementById('chart_holder');
	//remove canvas if present
			while (in_canvas.hasChildNodes()) {
				  in_canvas.removeChild(in_canvas.lastChild);
				} 
	//insert canvas
			var newDiv = document.createElement('canvas');
			in_canvas.appendChild(newDiv);
			newDiv.id = "myChart";
