Oxyplot in UWP Xamarin not updating

Question

I can't seem to bind correctly to Oxyplot in Xamarin. I had a read through multiple posts, but couldn't figure out what's wrong with my setup.

XAML

<ContentPage.BindingContext>
    <local:MainViewModel />
</ContentPage.BindingContext>

<ContentPage.Content>
    
    <Grid>

        <Grid.RowDefinitions>
            <RowDefinition Height="500" />
        </Grid.RowDefinitions>

        <oxy:PlotView Grid.Row="0" Model="{Binding CandlestickPlotModel}" Background="Green"/>
        
    </Grid>
    
</ContentPage.Content>

ViewModel

class MainViewModel
{
    public PlotModel CandlestickPlotModel { get; set; }

    public MainViewModel()
    {
        CandlestickPlotModel = new PlotModel();

        CandlestickPlotModel.Title = "Title";
        CandlestickPlotModel.Background = OxyColors.LightBlue;
    }
}

When I run, I get a green box, but I would expect a light blue box if the binding would work. Can anyone see what's wrong with this code?

Have you tried providing some Height and Width requests to the PlotView, or are you just assuming it will fill whatever area is available? — Cheesebaron, Nov 29 '20 at 01:03
I have tried, that doesn't seem to be the issue. I did have a size problem, so I didn't even get a green background. I resolved that, I get a background alright, but the viewmodel doesn't seem to bind properly. I'm starting to wonder if it's a version issue. — christian.stock, Nov 29 '20 at 06:18

Figured it out. Nothing wrong with the Binding. Oxyplot 1.0 and Xamarin Forms and UWP isn't supported. Installing Oxyplot.Xamarin.Forms 1.1.0-unstable fixes the issue.
