Hi Team,

Is it possible to stack or group series on the DonutSeries?

Is there a way to add borderstyle instead of the background color?

Please see screenshot.

Hi Andrew,

The data passed to Donut/Pie chart is actually added to one series, which is just visually displayed as separate ones, thus stacking/grouping in these chart types is currently not possible.

As for the border set to the series, there is an already feature request for the same, so you can vote for it here:

https://feedback.telerik.com/aspnet-ajax/1373488

In the item above you can see also a sample on how you can set a border through the Kendo widget of the chart:

Javascript:
	<script language="javascript">
		function pageLoad() {
			var chart = $find("RadHtmlChart1");
			chart._chartObject.options.series[0].border = {
				width: 2,
				color: "black",
				dashType: "dash",
				opacity: 0.2
			}
			chart.repaint();
		}
	</script>

ASPX:
	<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server" Width="600" Height="400">
		<PlotArea>
			<Series>
				<telerik:ColumnSeries>
					<SeriesItems>
						<telerik:CategorySeriesItem Y="30" />
						<telerik:CategorySeriesItem Y="10" />
						<telerik:CategorySeriesItem Y="20" />
					</SeriesItems>
				</telerik:ColumnSeries>
			</Series>
		</PlotArea>
	</telerik:RadHtmlChart>

Thanks for your quick responses.

could you please send an image of this working, because I just tested the code and can't really see the dash lines, could you also please do it in Donutseries instead of a Columnseries.

Thanks
