Line Smoothness

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 CommunityToolkit.Mvvm.ComponentModel;
using LiveChartsCore;
using LiveChartsCore.SkiaSharpView;

namespace ViewModelsSamples.Lines.Straight;

[ObservableObject]
public partial class ViewModel
{
    public ISeries[] Series { get; set; } =
    {
        new LineSeries<double>
        {
            Values = new double[] { 5, 0, 5, 0, 5, 0 },
            Fill = null,
            GeometrySize = 0,
            // use the line smoothness property to control the curve
            // it goes from 0 to 1
            // where 0 is a straight line and 1 the most curved
            LineSmoothness = 0 // mark
        },
        new LineSeries<double>
        {
            Values = new double[] { 7, 2, 7, 2, 7, 2 },
            Fill = null,
            GeometrySize = 0,
            LineSmoothness = 1 // mark
        }
    };
}

Form code behind

using System.Windows.Forms;
using LiveChartsCore.SkiaSharpView.WinForms;
using ViewModelsSamples.Lines.Straight;

namespace WinFormsSample.Lines.Straight;

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,

            // 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);
    }
}
