using System.Linq; 

// get the control in the UI
var chartControl = (CartesianChart)FindName("cartesianChart"); // notice this code is WPF specific

chartControl.UpdateStarted +=
    (LiveChartsCore.Kernel.Sketches.IChartView<LiveChartsCore.SkiaSharpView.Drawing.SkiaSharpDrawingContext> chart) =>
    {
        var x = chartControl.XAxes.First();

### View class: Set up CartesianChart with MatchAxesScreenDataRatio

Source: https://livecharts.dev/docs/Eto/2.0.4/samples.axes.matchScale

Creates a Panel containing a CartesianChart. Sets MatchAxesScreenDataRatio to true so both axes use the same pixels per data unit. Configures axes with MinStep and ForceStepToMin to highlight the equal scaling, and disables tooltip.

```csharp

### Chart.Series and Series.Values Change Detection Examples

Source: https://livecharts.dev/docs/Avalonia/2.0.4/Overview.How%20it%20works

Examples demonstrating how different collection types and property implementations affect automatic chart updates.

```csharp
// CHART.SERIES 

// in this case, the chart will not fire an update
// since List.Add() is not invoking INotifyCollectionChanged.CollectionChanged event
myChart.Series = new List<ISeries>();
myChart.Series.Add(new LineSeries() { Values = new []{ 1, 2, 3} });

// in this case it will update the chart
// since the ObservableCollection class provided by .Net
// already implements the INotifyCollectionChanged interface
myChart.Series = new ObservableCollection<ISeries>();
myChart.Series.Add(new LineSeries() { Values = new []{ 1, 2, 3} });

// for both previous cases
// the LineSeries class, already implements INotifyPropertyChanged
// this means that updating any property in the series will redraw the chart.
myChart.Series[0].Values = new []{ 4, 5, 6}; // this will fire an update




// SERIES.VALUES

// the following sample will not fire an update
// since the City class does not implements INotifyPropertyChanged
public class City
{
  public double Population { get; set; }
}

var seriesCollection = new List<ISeries>();
var lineSeries = new LineSeries 
{ 
  Values = new List<City> 
  { 
    new City { Population = 10 }, 
    new City { Population = 20 } 
  } 
};

lineSeries.Values[0].Population = 20; // will NOT update the chart

myChart.Series = seriesCollection;




// finally the next sample will update the chart automatically
// since the City class implements INotifyPropertyChanged
public class City : INotifyPropertyChanged
{
  private double? population;

  public double Population { get => population; set { population = value; OnPropertyChanged(); } }

  protected virtual void OnPropertyChanged([CallerMemberName] string? propertyName = null)
  {
    PropertyChanged?.Invoke(propertyName, new PropertyChangedEventArgs(propertyName));
  }
}

var seriesCollection = new List<ISeries>();
var lineSeries = new LineSeries 
{ 
  Values = new List<City> 
  { 
    new City { Population = 10 }, 
    new City { Population = 20 } 
  } 
};

lineSeries.Values[0].Population = 20; // will UPDATE the chart

myChart.Series = seriesCollection;

// the library already provides many ready to use objects that will update the chart automatically
// for example, the ObservableValue class
// https://github.com/beto-rodriguez/LiveCharts2/blob/master/src/LiveChartsCore/Defaults/ObservableValue.cs

### Implement theme-aware visual elements

Source: https://livecharts.dev/docs/Avalonia/2.0.4/samples.general.visualElements

Illustrates how to apply different styles based on the application theme, specifically detecting dark and light variants on supported platforms like Avalonia, Maui, Uno, and WinUI.

```csharp
using LiveChartsCore;
using LiveChartsCore.SkiaSharpView.Drawing.Geometries;
using LiveChartsCore.SkiaSharpView.Painting;
using LiveChartsCore.Themes;
using LiveChartsCore.VisualElements;
using SkiaSharp;

namespace ViewModelsSamples.General.VisualElements;

public class ThemedVisual : Visual
{
    private object _themeId = new();
    private static bool _isThemeRegistered;

    protected override RectangleGeometry DrawnElement { get; } =
        new RectangleGeometry();

    protected override void Measure(Chart chart)
    {
        if (!_isThemeRegistered) RegisterTheme();

        ApplyTheme(chart.GetTheme());

        DrawnElement.X = 600;
        DrawnElement.Y = 100;
        DrawnElement.Width = 40;
        DrawnElement.Height = 40;
    }

    private void ApplyTheme(Theme theme)
    {
        if (theme.ThemeId == _themeId) return;

        theme.ApplyStyleTo<ThemedVisual>(this);
        _themeId = theme.ThemeId;
    }

    private void RegisterTheme()
    {
        // now lets define the default style for the visual
        // ideally you should do this in the application startup

        var theme = LiveCharts.DefaultSettings.GetTheme();

        theme.HasRuleFor<ThemedVisual>(visual =>
        {
            visual.DrawnElement.Fill =
                theme.IsDark
                    ? new SolidColorPaint(SKColors.White)
                    : new SolidColorPaint(SKColors.Black);
        });

        _isThemeRegistered = true;
    }
}
```

### DateTimeScaled axes example for Eto.Forms

Source: https://livecharts.dev/docs/Eto/2.0.4/samples.axes.dateTimeScaled

The example creates a Cartesian chart with a DateTimeAxis, using a day unit and a custom date formatter to display the month and day.

```C#
using System;
using Eto.Forms;
using LiveChartsCore;
using LiveChartsCore.Defaults;
using LiveChartsCore.SkiaSharpView;
using LiveChartsCore.SkiaSharpView.Eto;

namespace EtoFormsSample.Axes.DateTimeScaled;

public class View : Panel
{
    private readonly CartesianChart cartesianChart;

    public View()
    {
        var values = new DateTimePoint[]
        {
            new() { DateTime = new DateTime(2021, 1, 1), Value = 3 },
            new() { DateTime = new DateTime(2021, 1, 2), Value = 6 },
            new() { DateTime = new DateTime(2021, 1, 3), Value = 5 },
            new() { DateTime = new DateTime(2021, 1, 4), Value = 3 },
            new() { DateTime = new DateTime(2021, 1, 5), Value = 5 },
            new() { DateTime = new DateTime(2021, 1, 6), Value = 8 },
            new() { DateTime = new DateTime(2021, 1, 7), Value = 6 }
        };

        static string Formatter(DateTime date) => date.ToString("MMMM dd");

        var series = new ISeries[]
        {
            new ColumnSeries<DateTimePoint> { Values = values }
        };

        var xAxis = new DateTimeAxis(TimeSpan.FromDays(1), Formatter);

        cartesianChart = new CartesianChart
        {
            Series = series,
            XAxes = [xAxis],
        };

        Content = cartesianChart;
    }
}

### Basic Step Line Chart Implementation

Source: https://livecharts.dev/docs/Eto/2.0.4/samples.steplines.basic

This example demonstrates how to define a StepLineSeries with a set of double values and add it to a CartesianChart within an Eto.Forms Panel.

```csharp
using Eto.Forms;
using LiveChartsCore;
using LiveChartsCore.SkiaSharpView;
using LiveChartsCore.SkiaSharpView.Eto;
using LiveChartsCore.SkiaSharpView.Painting;
using SkiaSharp;
using LiveChartsCore.SkiaSharpView.VisualElements;
using LiveChartsCore.SkiaSharpView.Drawing.Geometries;

namespace EtoFormsSample.StepLines.Basic;

public class View : Panel
{
    public View()
    {
        var values = new double[] { 2, 1, 3, 4, 3, 4, 6 };

        var series = new ISeries[]
        {
            new StepLineSeries<double>
            {
                Values = values,
                Fill = null,
                GeometrySize = 20
            }
        };

        var title = new DrawnLabelVisual(
            new LabelGeometry
            {
                Text = "My chart title",
                Paint = new SolidColorPaint(SKColor.Parse("#303030")),
                TextSize = 25,
                Padding = new LiveChartsCore.Drawing.Padding(15)
            });

        var cartesianChart = new CartesianChart
        {
            Series = series,
            Title = title
        };

        Content = cartesianChart;
    }
}
```
