How to customize the individual legend item based on a condition in Xamarin.Forms Chart?

1 min read

You can customize all the legend items by setting individual style using the LegendItemCreated event. This event will be fired when a Xamarin Chart legend item is created. For more details about the event arguments, refer to this documentation.

The following code sample demonstrates how to set individual style to all the legend items and you can download the complete sample here.


<chart:SfChart x:Name="chart" LegendItemCreated="Chart_LegendItemCreated">


chart.LegendItemCreated += Chart_LegendItemCreated;
private void Chart_LegendItemCreated(object sender, ChartLegendItemCreatedEventArgs e)
   Model model = e.LegendItem.DataPoint as Model;
   e.LegendItem.Label = model.XValue + ": " + model.YValue.ToString();
   e.LegendItem.LabelStyle = new ChartLegendLabelStyle()
        TextColor = model.YValue > 50 ? Color.Green : Color.Red,
        FontFamily = model.YValue > 50 ? "Times New Roman" : "Arial"
