labelWrap: Boolean

Setting labelWrap to true wraps the labels at labelMaxWidth. Clips the same when set to false. It overrides the labelWrap set at axis level.

var  chart =  new  CanvasJS.Chart("container",
{
 .
 .
 axisY:{
	stripLines: [
		{
		 labelWrap: true  // change to false
		 labelMaxWidth: 50
			
		}
	]
   },
 .
 . 
});
chart.render();
