I found a few threads where Telerik responded that this feature was being implemented, and the threads were from around 2014 I think.  I have not found any threads with examples of how this is done, so not sure if it was ever implemented?  An example of what I'm looking for is attached.

Thanks

Ok, so I got the wrapping.  Related question, is there a way to turn off the labels of the inner circle in a nested donut chart?  or have the inner pieces be tooltips and outer pieces be labeled?  See attached chart for problem.

I work in MVC and find it difficult to translate from razor syntax to jquery for kendo elements.

Here is the data:

[
{
ID: 13315,
category: "High Yield Bond",
value: 0.1,
GroupName: "Class",
color: "#7198FF",
IsClass: true
},
{
ID: 43360,
category: "BIL",
value: 0.1,
GroupName: "Product",
color: "#7198FF",
IsClass: false
},
{
ID: 13319,
category: "Large Blend",
value: 0.3,
GroupName: "Class",
color: "#DE5A43",
IsClass: true
},
{
ID: 42686,
category: "IVV",
value: 0.15,
GroupName: "Product",
color: "#DE5A43",
IsClass: false
},
{
ID: 70860,
category: "Raub Brock Dividend Growth",
value: 0.15,
GroupName: "Product",
color: "#BC4C38",
IsClass: false
},
{
ID: 13321,
category: "Large Value",
value: 0.3,
GroupName: "Class",
color: "#618DBE",
IsClass: true
},
{
ID: 272,
category: "Federated Strat Value Dividend",
value: 0.3,
GroupName: "Product",
color: "#618DBE",
IsClass: false
},
{
ID: 13333,
category: "Small Growth",
value: 0.1,
GroupName: "Class",
color: "#81ddf1",
IsClass: true
},
{
ID: 70447,
category: "Bahl & Gaynor Small Cap Quality Growth",
value: 0.1,
GroupName: "Product",
color: "#81ddf1",
IsClass: false
},
{
ID: 13338,
category: "World Stock",
value: 0.1,
GroupName: "Class",
color: "#6ec5ab",
IsClass: true
},
{
ID: 70414,
category: "HJIM International Select",
value: 0.1,
GroupName: "Product",
color: "#6ec5ab",
IsClass: false
},
{
ID: 13407,
category: "Volatility",
value: 0.1,
GroupName: "Class",
color: "#499aa6",
IsClass: true
},
{
ID: 70421,
category: "12th Street Asset Opportunity",
value: 0.1,
GroupName: "Product",
color: "#499aa6",
IsClass: false
}
]

and here is the razor cshtml:

@(Html.Kendo().Chart<APLiteModels.Charts.AllocationChartItem>()
     .Name("allocation")
     .ChartArea(chartArea => chartArea
         .Background("transparent")
         .Margin(0)
         .Height(300))
     .PlotArea(plotArea => plotArea.Margin(0))
     .Title(title => title
         .Position(ChartTitlePosition.Top)
         .Color("#FFFFFF")
         .Margin(0)
         .Padding(0)
     )
     .Legend(legend => legend
         .Visible(false)
     )
     .SeriesColors(APLiteCore.ThemeHelper.AllChartTheme)
     .SeriesDefaults(series =>
         series.Donut().StartAngle(150)
     )
     .DataSource(dataSource => dataSource
         .Group(group => group.Add(item => item.GroupName))
                     .Read(read => read.Action("AllocationPieChartData", "Investments").Data("sendId"))
     )
     .Series(series =>
     {
         series.Donut("value", "category")
         .Size(35)
         .Name("Allocations")
         .Overlay(ChartPieSeriesOverlay.None)
         .Labels(labels => labels
                         .Template("#= category # : #= kendo.format('{0:P}', percentage) #")
                         .Background("transparent")
                         .Visible(true)
                         .Align(ChartPieLabelsAlign.Circle)
                         .Position(ChartPieLabelsPosition.OutsideEnd)
                     );
     })
 
     .Tooltip(tooltip => tooltip
         .Visible(false)
         .Template("#= category # : #= kendo.format('{0:P}', percentage) #")
     )
 )

Hi Robert,

 

You can try to use the visual or template capability provided by the Kendo Chart's series.labels API:
https://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart/configuration/series.labels.visual

Feel free to give it a try and let me know if it works for you.
