How to present WPF Oxyplot on new window

Question

I've been playing around with trying to plot a boxplot using Oxyplot in WPF. I've managed to get a nice graph working in a completely new project, and am now attempting to show a similar graph in a new window of a project I'm currently working on and I'm not managing to get anything to show up. It's probably something very obvious, but I'm a bit lost. Here's where I'm at.

New Window I'm trying to open:
XAML

<Window x:Class="Data_Mining_Over_Cancer_Data.DistancePlots"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:oxy="http://oxyplot.org/wpf"
    xmlns:local="clr-namespace:Data_Mining_Over_Cancer_Data"
    mc:Ignorable="d"
    Title="DistancePlots" Height="300" Width="300">
<Window.DataContext>
    <local:DistancePlots/>
</Window.DataContext>
<Grid>
    <oxy:PlotView Model="{Binding MyModel}"/>
</Grid>

Code

public partial class DistancePlots : Window

    public DistancePlots()
    {
        //InitializeComponent();
        DistanceBoxPlotSeries plots = new DistanceBoxPlotSeries();
        this.MyModel = plots.CreateBoxPlot();

            var values = new List<double>();
            for (int j = 0; j < points; j++)

Opening the new window from the main window:

 private void PlotButton_Click(object sender, RoutedEventArgs e)
    {
        DistancePlots plots = new DistancePlots();
        plots.Show();
    }

Currently this opens the new window, but the graph isn't showing up. If I use the exact same code in the main window of a project, it works. My understanding of WPF data binding is quite limited, so I think something could be going wrong there?
Any help would be greatly appreciated. Cheers
