Grouped And Stacked Bars
This web site builds the control from code behind but you could also grab it from the toolbox, this sample also uses a ViewModel to populate the properties of the control(s) in this sample.

View model
using System.Collections.Generic;
using CommunityToolkit.Mvvm.ComponentModel;
using LiveChartsCore;
using LiveChartsCore.SkiaSharpView;
namespace ViewModelsSamples.StackedBars.Groups;
[ObservableObject]
public partial class ViewModel
{
public ISeries[] Series { get; set; } =
{
new StackedColumnSeries<int>
{
Values = new List<int> { 3, 5, 3 },
Stroke = null,
StackGroup = 0 // mark
},
new StackedColumnSeries<int>
{
Values = new List<int> { 4, 2, 3 },
Stroke = null,
StackGroup = 0 // mark
},
new StackedColumnSeries<int>
{
Values = new List<int> { 4, 6, 6 },
Stroke = null,
StackGroup = 1 // mark
},
new StackedColumnSeries<int>
{
Values = new List<int> { 2, 5, 4 },
Stroke = null,
StackGroup = 1 // mark
}
};
public Axis[] XAxis { get; set; } =
{
new Axis
{
LabelsRotation = -15,
Labels = new[] { "Category 1", "Category 2", "Category 3" }
}
};
}
Form code behind

// out of livecharts properties...

Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top | AnchorStyles.Bottom
};
Controls.Add(cartesianChart);
