How to group stacking series in .NET MAUI SfCartesianChart

This article explains how to group the stacking series in .NET MAUI Cartesian Chart

A stacked chart is a type of graph that displays multiple data series on top of one another, allowing you to see the total and individual contributions of each series to the whole. The .NET MAUI Cartesian Chart provide support to cluster the stacking series using the GroupingLabel property.

Consider a scenario with four stacking column series grouped into two entities, namely GroupOne and GroupTwo, distinguished by the GroupingLabel property. In the resulting chart, two stacking columns are rendered at a specific point— one representing GroupOne and the other representing GroupTwo. Specifically, TeamA and TeamB are associated with GroupOne, while TeamC and TeamD are affiliated with GroupTwo.

Overview

In Syncfusion .NET MAUI Charts, the SfCartesianChart control supports grouped stacking for series such as StackingColumnSeries, StackingBarSeries, and StackingAreaSeries. Grouped stacking allows multiple series to be stacked independently within the same chart, enabling comparative analysis across different categories or groups.

Use Cases

• Comparative Analysis: Compare multiple categories side-by-side while maintaining stacked values within each group.
• Sales by Region and Product: Group series by region and stack product sales within each region.
• Budget vs Actual: Stack budgeted and actual values separately for different departments.
• Multi-Year Data: Group series by year and stack monthly data within each year.
• Segmented Performance: Visualize performance metrics grouped by teams or business units.

XAML

<chart:SfCartesianChart>
       ...
       <chart:StackingColumnSeries ItemsSource="{Binding Data1}"
                                   XBindingPath="Month"
                                   YBindingPath="Value"
                                   Label="Team A"
                                   GroupingLabel="GroupOne">
       </chart:StackingColumnSeries>
       
       <chart:StackingColumnSeries ItemsSource="{Binding Data2}"
                                   XBindingPath="Month"
                                   YBindingPath="Value"
                                   Label="Team B"
                                   GroupingLabel="GroupOne">
       </chart:StackingColumnSeries>
       
       <chart:StackingColumnSeries ItemsSource="{Binding Data3}"
                                   XBindingPath="Month"
                                   Label="Team C"
                                   GroupingLabel="GroupTwo">
       </chart:StackingColumnSeries>

       <chart:StackingColumnSeries ItemsSource="{Binding Data4}"
                                   XBindingPath="Month"
                                   YBindingPath="Value"
                                   Label="Team D"
                                   GroupingLabel="GroupTwo">
       </chart:StackingColumnSeries>
       ...      
</chart:SfCartesianChart>

C#

   SfCartesianChart chart = new SfCartesianChart();
   ...
   
   var teamASeries = new StackingColumnSeries
   {
       ItemsSource = "{Binding Data1}",
       XBindingPath = "Month",
       YBindingPath = "Value",
       Label="Team A",
       GroupingLabel="GroupOne"
   };
   
   var teamBSeries  = new StackingColumnSeries
   {
       ItemsSource = "{Binding Data2}",
       XBindingPath = "Month",
       YBindingPath = "Value",
       Label="Team B",
       GroupingLabel="GroupOne"
   };
   
   var teamCSeries  = new StackingColumnSeries
   {
       ItemsSource = "{Binding Data3}",
       XBindingPath = "Month",
       YBindingPath = "Value",
       Label="Team C",
       GroupingLabel="GroupTwo"
   };
   
   var teamDSeries  = new StackingColumnSeries
   {
       ItemsSource = "{Binding Data4}",
       XBindingPath = "Month",
       YBindingPath = "Value",
       Label="Team D",
       GroupingLabel="GroupTwo"
   };
   
   chart.Series.Add(teamASeries);
   chart.Series.Add(teamBSeries);
   chart.Series.Add(teamCSeries);
   chart.Series.Add(teamDSeries);
   
   this.Content=chart;
