chart tooltip: hide undefined

[pancakestacks]

Hi,

I’m looking to hide undefined sections in my tooltips.

Since one of the categories is an unique serial number, and not all products have one, I have many undefined values.

I was wondering what code should I input. I currently have:

	toolTip: {
		animationEnabled: false,
		backgroundColor: "white",
	
			var label = "";
			var content = " ";
			for (var i = 0; i < e.entries.length; i++) {
				content += "x:" + e.entries[i].dataPoint.x + "VP" + e.entries[i].dataPoint.y + " " + e.entries[i].dataPoint.serial_number;
			}

@pancakestacks,

You can add a condition to check if the category serial_number is present in toolTip contentFormatter. Please take a look at this jsfiddle.
