Gruped 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

using System.Windows.Forms;
using LiveChartsCore.SkiaSharpView.WinForms;
using ViewModelsSamples.StackedBars.Groups;

namespace WinFormsSample.StackedBars.Groups;

public partial class View : UserControl
{
    private readonly CartesianChart cartesianChart;

    public View()
    {
        InitializeComponent();
        Size = new System.Drawing.Size(50, 50);

        var viewModel = new ViewModel();

        cartesianChart = new CartesianChart
        {
            Series = viewModel.Series,
            XAxes = viewModel.XAxis,

            // out of livecharts properties...
            Location = new System.Drawing.Point(0, 0),
            Size = new System.Drawing.Size(50, 50),
            Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top | AnchorStyles.Bottom
        };

        Controls.Add(cartesianChart);
    }
}
