Hi Lakhwinder,

We can achieve your requirement by using the property ColorModel in the Series. Refer to the following code example which shows how to set ColorModel in series.

CodeExample:

SFPieSeries series = new SFPieSeries ();
series.ColorModel.Palette = SFChartColorPalette.Custom;
NSObject[] cusColors = new NSObject[] {UIColor.Blue,UIColor.Green,UIColor.Orange,UIColor.Red,UIColor.Cyan};
series.ColorModel.CustomColors = NSArray.FromNSObjects(cusColors);
series.DataMarker.ShowLabel = true;
return series;

We have prepared a sample based on your requirement. Please find the sample from the following location.

I did it in XAML:


<chart:PieSeries ItemsSource="{Binding HighTemperature}" >

                        <chart:PieSeries.ColorModel>

                            <chart:ChartColorModel Palette="Custom" >

                                <chart:ChartColorModel.CustomBrushes>

                                    <Color>

                                        Red

                                    </Color>

                                    <Color>

                                        Yellow

                                    </Color>

                                    <Color>

                                        Green

                                    </Color>

                                </chart:ChartColorModel.CustomBrushes>

                            </chart:ChartColorModel>

                        </chart:PieSeries.ColorModel>

                        

                        

                        <chart:PieSeries.DataMarker>

                            <chart:ChartDataMarker ShowLabel="True"></chart:ChartDataMarker>

                        </chart:PieSeries.DataMarker>


                    </chart:PieSeries>

Hi Macro, 
 
We have prepared the sample based on your provided code snippet to change the color of PieChart. Please find the sample from following location. 
 
 
Custom Brushes: 
 
ChartSeries will use the colors from CustomBrushes property if the ColorModel.Palette property of series is set to Custom 
 
Also, you can change the PieChart color using predefined palettes available in ColorModel property of ChartSeries as listed below. 
 
1.     Metro 
2.     TomatoSpectrum 
3.     Pineapple 
4.     None 
 
Please find the below code snippet for more details. 
 
Code Snippet: 
 
  
      <chart:PieSeries.ColorModel> 
        <chart:ChartColorModel Palette=" TomatoSpectrum" > 
     </chart:PieSeries.ColorModel> 
 
 
Please let us know, if you need further assistance on this.   
 
Regards,
Parthiban S
