How to apply custom fonts to chart elements in .NET MAUI Chart?

5 mins read

Custom fonts refer to typefaces that are not part of the standard font collections available on OS. They are unique or specifically designed fonts that differ from common system fonts like Arial, Times New Roman…etc . We can apply different custom font families to individual text elements in the .NET MAUI SfCartesian Chart. The following steps describe how to achieve this:

Step 1:

Initialize SfCarteainChart using the guidelines document.

Step 2:

Download the required custom font files and place them in the fonts folder of your sample with the extension .ttf.

Step 3:

In the MauiProgram.cs class, configure the custom font files with name using the following format:

public static MauiApp CreateMauiApp()
{
       .ConfigureFonts(fonts =>
       {
           fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
           fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
           fonts.AddFont("Pacifico.ttf", "Pacifico");
           fonts.AddFont("FFFTusj.ttf", "FFFTusj");
           fonts.AddFont("Windsong.ttf", "Windsong");
       });
}

Step 4:

Apply the desired custom fonts to specific chart elements by binding their names to the font family as demonstrated below:

XAML

<chart:SfCartesianChart>
   <!--Chart Title-->
   <chart:SfCartesianChart.Title>
       <Label Text="Tasks Completed VS Target by Month"
                    FontSize="17"
                    FontFamily="Pacifico"/>
   </chart:SfCartesianChart.Title>
   

<!--Axis Labels-->
<chart:SfCartesianChart.XAxes>
   <chart:CategoryAxis>
       <chart:CategoryAxis.Title>
           <chart:ChartAxisTitle Text="Month"
                                 FontFamily="Pacifico"
                                 TextColor="Black"/>
       </chart:CategoryAxis.Title>
       <chart:CategoryAxis.LabelStyle>
           <chart:ChartAxisLabelStyle FontSize="17"
                                      FontAttributes="Bold"/>
       </chart:CategoryAxis.LabelStyle>
   </chart:CategoryAxis>
</chart:SfCartesianChart.XAxes>

<chart:SfCartesianChart.YAxes>
   <chart:NumericalAxis>
       <chart:NumericalAxis.Title>
           <chart:ChartAxisTitle Text="Counts"
                                 FontFamily="Pacifico"/>
       </chart:NumericalAxis.Title>
       <chart:NumericalAxis.LabelStyle>
           <chart:ChartAxisLabelStyle FontFamily="Windsong" 
                                      FontSize="17"
                                      TextColor="Black"
                                      FontAttributes="Bold"/>
       </chart:NumericalAxis.LabelStyle>
   </chart:NumericalAxis>
</chart:SfCartesianChart.YAxes>


<!--Data Label-->
<chart:ColumnSeries ItemsSource="{Binding TaskStatus}"
                   XBindingPath="Month" 
                   YBindingPath="TargetCount"
                   ShowDataLabels="True" >  
   <chart:ColumnSeries.DataLabelSettings>
       <chart:CartesianDataLabelSettings>
           <chart:CartesianDataLabelSettings.LabelStyle>
               <chart:ChartDataLabelStyle FontFamily="FFFTusj"
                                          FontSize="15"/>
           </chart:CartesianDataLabelSettings.LabelStyle>
       </chart:CartesianDataLabelSettings>
   </chart:ColumnSeries.DataLabelSettings>
</chart:ColumnSeries>
…
</chart:SfCartesianChart>

SfCartesianChart chart = new SfCartesianChart();

//Chart Title
chart.Title = new Label
{
   Text = "Tasks Completed VS Target by Month",
   FontSize = 17,
   FontFamily = "Pacifico",
};

CategoryAxis primaryAxis = new CategoryAxis();

//Chart Axis Title
primaryAxis.Title = new ChartAxisTitle
{
   Text = "Month",
   FontFamily = "Pacifico"
};
//Chart Axis Label
primaryAxis.LabelStyle.FontFamily = "Windsong";
primaryAxis.LabelStyle.FontSize = 17;
primaryAxis.LabelStyle.FontAttributes = FontAttributes.Bold;
chart.XAxes.Add(primaryAxis);


NumericalAxis secondaryAxis = new NumericalAxis();
//Chart Axis Title
secondaryAxis.Title = new ChartAxisTitle
{
   Text = "Counts",
   FontFamily = "Pacifico"
};
//Chart Axis Label
secondaryAxis.LabelStyle.FontFamily = "Windsong";
secondaryAxis.LabelStyle.FontSize = 17;
secondaryAxis.LabelStyle.FontAttributes = FontAttributes.Bold;
chart.YAxes.Add(secondaryAxis);


//Data Label 
ColumnSeries series = new ColumnSeries()
{

   ItemsSource = (new ViewModel()).TaskStatus,
   XBindingPath = "Month",
   YBindingPath = "TargetCount",
   ShowDataLabels= true,
              
};
series.DataLabelSettings = new CartesianDataLabelSettings();
series.DataLabelSettings.LabelStyle.FontFamily = "FFFTusj";                                             
series.DataLabelSettings.LabelStyle.FontSize = 15;

…
chart.Series.Add(series);
this.Content = chart;
