Overview

The WinUI Line Chart represents and visualizes time-dependent data to show trends at equal intervals. It supports numeric, category, date-time, and logarithmic axes, and works well with large amounts of data with animation, zooming, and panning.

{
    public string Month { get; set; }

    public double Target { get; set; }

    public Model(string xValue, double yValue)
    {
        Month = xValue;
        Target = yValue;
    }
}

public class ViewModel
{
    public ObservableCollection<Model> Data { get; set; }

    public ViewModel()
    {
        Data = new ObservableCollection<Model>()
        {
            new Model("Jan", 50),
            new Model("Feb", 70),
            new Model("Mar", 65),
            new Model("Apr", 57),
            new Model("May", 48), 
        };
    }
