How to create square plot area with Oxyplot

Question

I'm trying to create a square graph (X axis width is the same as the Y axis height).

I can't find any documentation on this and all of the properties I've seen which might be able to do this are inaccessible.

I've tried:

<oxy:PlotView Model="{Binding Model}" Width="500" Height="500"/>

This obviously doesn't work because this sets the entire area (not the graph specific portion).

Answer 1

I solved this by hooking into the LayoutUpdated event on the PlotView and updating the PlotView.Width from the PlotArea width/height difference.

XAML:

<Window x:Class="Temp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:oxy="http://oxyplot.org/wpf"
        Title="MainWindow" Width="500" Height="500">
    <Grid>
        <oxy:PlotView Model="{Binding PlotModel}" x:Name="PlotView"/>
    </Grid>
</Window>

Code Behind:

public partial class MainWindow
    {
        public MainWindow()
        {
            InitializeComponent();

            DataContext = new MainViewModel();
        }

        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();

            var plotView = (PlotView) this.FindName("PlotView");

            plotView.LayoutUpdated += OnLayoutUpdated;
        }

        private void OnLayoutUpdated(object sender, EventArgs e)
        {
            var plotView = (PlotView) this.FindName("PlotView") ;

            if (plotView.Model != null)
            {
                var widthAdjustment = plotView.Model.PlotArea.Width - plotView.Model.PlotArea.Height;

                plotView.Width = plotView.ActualWidth - widthAdjustment;
            }
        }
    }
