The .NET MAUI Charts control is a well-crafted charting control for visualizing data. It contains a rich gallery of 10+ charts and graphs that cater to all charting scenarios.
In this blog post, I’ll quickly introduce the new features included in the .NET MAUI Charts control for the 2022 Volume 3 release.
Logarithmic axis
When the largest and smallest values in a data collection are hundreds or even thousands of units apart, the logarithmic scale can be used to describe the data interval.
Our Syncfusion .NET MAUI Charts now support rendering a logarithmic axis. It can compactly display numerical data over a large range of values.
The following code example shows how to configure a logarithmic axis in a .NET MAUI Cartesian Chart.
Xaml
<chart:SfCartesianChart>
<chart:SfCartesianChart.XAxes>
<chart:LogarithmicAxis/>
</chart:SfCartesianChart.XAxes>
<chart:SfCartesianChart.YAxes>
<chart:LogarithmicAxis/>
</chart:SfCartesianChart.YAxes>
</chart:SfCartesianChart>
Series selection and multiselection
The .NET MAUI Charts control’s selection behavior highlights a particular element [data point or series] on the chart. In other words, this behavior selects a segment or series.
The following code shows how to configure series selection in a chart.
Xaml
<chart:SfCartesianChart>
. . .
<chart:SfCartesianChart.SelectionBehavior>
<chart:SeriesSelectionBehavior SelectionBrush="Green"/>
</chart:SfCartesianChart.SelectionBehavior>
<!--Series collection.-->
</chart:SfCartesianChart>
And the next code shows how to enable the selection of multiple series in .NET MAUI Charts.
Xaml
<chart:SfCartesianChart>
. . .
<chart:SfCartesianChart.SelectionBehavior>
<chart:SeriesSelectionBehavior Type="Multiple"/>
</chart:SfCartesianChart.SelectionBehavior>
<!--Series collection.-->
</chart:SfCartesianChart>
Explode segment on touch
Now, you can pop out a particular segment of a circular chart (pie and doughnut) with a touching or tapping interaction. The following code example shows how to configure a segment to explode on touch.
Xaml
<chart:SfCircularChart>
. . .
<chart:DoughnutSeries ExplodeOnTouch="True" />
</chart:SfCircularChart>
View in center of doughnut charts
You can place any view in the middle of a doughnut chart. This helps us show more information about the chart data. The following code example shows how to configure the doughnut chart’s center view.
Xaml
<chart:SfCircularChart>
<chart:SfCircularChart.Series>
<chart:DoughnutSeries ItemsSource="{Binding DoughnutSeriesData}" XBindingPath="Name" YBindingPath="Value"/>
<chart:DoughnutSeries.CenterView>
<Label Text = "{Binding Total, Source={x:Reference doughnutViewModel}}"/>
</chart:DoughnutSeries.CenterView>
</chart:SfCircularChart.Series>
</chart:SfCircularChart>
Chart plot area background
Add any view to the chart area. This comes in handy for including relevant information, a watermark, or a color gradient in the chart’s background area.
The following code example shows how to configure the .NET MAUI Cartesian Chart’s plot area background view.
Xaml
<chart:SfCartesianChart>
<chart:SfCartesianChart.PlotAreaBackgroundView>
<AbsoluteLayout>
<Label Text=" Copyright © 2001 - 2022 Syncfusion Inc "
FontSize="18"
AbsoluteLayout.LayoutBounds="1,1,-1,-1"
AbsoluteLayout.LayoutFlags="PositionProportional"
Opacity="0.4" />
<Label Text="CONFIDENTIAL"
Rotation="340"
AbsoluteLayout.LayoutBounds="0.5,0.5,-1,-1"
AbsoluteLayout.LayoutFlags="PositionProportional"
Opacity="0.3" />
</AbsoluteLayout>
</chart:SfCartesianChart.PlotAreaBackgroundView>
</chart:SfCartesianChart>
