Enhancement

Currently the dialog action buttons can not hold only icons, the API does not provide means to have a button with only an icon or an icon and text. Considering the aforementioned we should extend the API to allow adding of icons inside the action buttons.

var chart = $("#chart").data("kendoChart");
var series = [];

$(theData.Serieses).each(function (index) {
	series.push({
		name: theData.Serieses[index].Name,
		field: theData.Serieses[index].Name,
		data: theData.Serieses[index].SeriesPoints,
		xField: "X",
		yField: "Y",
		color: theData.Serieses[index].Colour,
		markers: {
			type: theData.Serieses[index].Shape
		}
	});
});
chart.setOptions({ series: series, noData: series.length == 0 });
chart.redraw();
console.log(chart.options);

When updating a chart after instantiation, because noData defaults to true, the overlay is shown immediately

if you try and set noData via setOptions then redraw(), the overlay is still in place

Honestly, this should have been marked as a breaking change as every single chart has to be updated to force noData to false just to show initially
