Asked On June 17, 2019 11:58 AM UTC

Hello,

My requirement is to draw the fact that a percentage has been overlapped and drow it using a doughnut chart. For example, given the circle as 100%, I have to color differently the fact that it went 105% by coloring the 5% in a different color. Something like in the image below. 
Is that possible using the Doghnut Chart ? 

Thank you

Hi Codrina, 
 
Greetings from Syncfusion. We can achieve your requirement by changing the color in TrackColor property when value exceed 100 as shown in the below code example. 
 
[C#] 
          if (value > 100) 
            { 
                TrackColor = Color.BlueViolet; 
                value = value % 100; 
            } 
            else 
            { 
                TrackColor = Color.Gray; 
            }             
 
[XAML] 
<chart:DoughnutSeries IsStackedDoughnut="True" TrackColor="{Binding TrackColor}" CapStyle="BothCurve" MaximumValue="100" Spacing="0.5" Color="Black" ItemsSource="{Binding DoughnuSeriesData}" XBindingPath="Percentage" YBindingPath="Value"> 
. . . 
 
    </chart:DoughnutSeries> 
 
 
Refer the below link to know more about doughnut configuration.  
 
Also, we have prepared sample you can download from below link. 
 
Regards, 
Rachel.
