Is there a way to create "callouts" for labels?

[daviddam]

We have an ask to have the values on a pie chart to be outside of the chart (rather than in the center of each piece).  Is this something natively supported, or are more involved methods required?  If so, can you point me in the right direction, please?

 Thanks!

Each of our gallery objects support specialization, in the case of pie, we have a couple of properties including the one you need. In code you would have to do

chart1.Gallery =

Gallery.Pie;ChartFX.WPF.Galleries.Pie pieAttributes = (ChartFX.WPF.Galleries.Pie) chart1.AllSeries.GalleryAttributes;pieAttributes.LabelsInside = false;

Note that the cast to ChartFX.WPF.Galleries.Pie will throw if you have not set the Gallery to Pie beforehand. If you have multiple series they will share the same attributes but you can also create Pie objects and assign them on a per-series basis. You can also do it in XAML as follows

<

cfx:Chart x:Name="chart1">  <cfx:Chart.AllSeries>   <cfx:AllSeriesAttributes>   <cfx:AllSeriesAttributes.GalleryAttributes>   <cfxGalleries:Pie LabelsInside="false"/>   </cfx:AllSeriesAttributes.GalleryAttributes>   </cfx:AllSeriesAttributes>  </cfx:Chart.AllSeries></cfx:Chart>

PS: There is a sizing issue with small charts when using outside labels because we have an alternate property that controls how small should the plotarea result. If you experience label clipping you might need to do this

chart1.PlotArea.MinSize = 0;

I forgot to say that if you use the XAML approach you need the following namespace at the root element in your xaml

xmlns:cfxGalleries="clr-namespace:ChartFX.WPF.Galleries;assembly=ChartFX.WPF"
