Format piechart percentage values without decimals

Good morning Marcus,

Pie chart labels can be formatted using a Custom class implementing SCIPieSegmentLabelFormatterBase

take a look at the Pie Chart documentation page here.

Pie Segment Label Formatter

By default, the Pie Segment Label displays a relative percentage
calculated on values of all segments in SCIPieDonutRenderableSeriesBase.segmentsCollection.
This behavior can be controlled and to do so you’ll need to subclass SCIPieSegmentLabelFormatterBase
and provide your custom data in ISCIPieSegmentLabelFormatter formatLabelForPieSegment method.
As an example, let’s create a label that displays a segment absolute
value. Assume, we create a donutSeries and add four segments with
values 40, 10, 20, and 15. Here is the code sample, how to do this:

class CustomPieSegmentLabelFormatter: SCIPieSegmentLabelFormatterBase {
      override func formatLabel(for pieSegment: ISCIPieSegment!) -> String! {
          return “\(pieSegment.value)”
      }
  }
  
  // Assume a donutSeries has been created somewhere
  let donutSeries = SCIDonutRenderableSeries()
  donutSeries.pieSegmentLabelFormatter = CustomPieSegmentLabelFormatter()
  

This produces the following output:

Please let me know if this helps
