How to customize the data label’s font in .NET MAUI Chart (SfCartesianChart)?

This article explains how to customize the font of the data labels in .NET MAUI Cartesian Charts. The .NET MAUI Chart allows you to customize the font of the data labels using the LabelStyle property of the ChartDataLabelSettings. This property provides options to change the font size, font family, font attributes, and label format of the data labels.

The following code demonstrates how to customize the font of the data labels.

XAML

<chart:SfCartesianChart>
. . .
   <chart:ColumnSeries ItemsSource="{Binding Data}" XBindingPath="Source" 
                           YBindingPath="Traffic" ShowDataLabels="True">
        <chart:ColumnSeries.DataLabelSettings>
            <chart:CartesianDataLabelSettings>
                <chart:CartesianDataLabelSettings.LabelStyle>
                    <chart:ChartDataLabelStyle FontSize="16" FontAttributes="None" 
                           FontFamily="OpenSans-Regular" LabelFormat="0.0M"/>
                </chart:CartesianDataLabelSettings.LabelStyle>
            </chart:CartesianDataLabelSettings>
        </chart:ColumnSeries.DataLabelSettings>
    </chart:ColumnSeries>
</chart:SfCartesianChart>

C#

SfCartesianChart chart = new SfCartesianChart();
. . .
ColumnSeries series = new ColumnSeries()
{
   ItemsSource = viewModel.Data,
   XBindingPath = "Source",
   YBindingPath = "Traffic",
   ShowDataLabels = true
};

series.DataLabelSettings.LabelStyle = new ChartDataLabelStyle()
{
   FontSize = 16,
   FontAttributes = FontAttributes.None,
   FontFamily = "OpenSans-Regular",
   LabelFormat = "0.0M"
};
