Axis lines are not drawn

[XamlBrewer]

If you make the PlotAreaBorderColor transparent, then you notice that not a single axis line is drawn. Setting an AxislineColor has no effect. This applies to all types, so it is not the same issue as #4. I don't see anyone observing this in the base OxyPlot repo. Here's a screenshot from my sample repo here:

Sorry I don't understand the expected behavior in this case

I'm testing the behavior on the official WPF version:

with model.PlotAreaBorderColor = OxyColors.Transparent;

without model.PlotAreaBorderColor = OxyColors.Transparent;

Can you point me if there is a problem in these screenshots?
If so, then you need to create an issue at https://github.com/oxyplot/oxyplot to fix it on all platforms.
At the moment, I support the UWP/WinUI/Uno platforms of this library, trying to match the WPF behavior of the main library with some of my own additions (like Dark Theme support).

But I definitely see a bug here :)

P.S. Fixed

@VisualMelon please check this issue

What I was expecting, is that there would be no border but axis lines would remain visible - as in the following screenshot from UWP:

[HavenDV]

Perhaps there is some configuration problem here? Because I wasn't able to achieve this behavior in WPF with any of the versions of OxyPlot.WPF.
Also, I couldn't find the AxislineColor property. What class is it in?

[XamlBrewer]

It's in the OxyPlot.Axes.Axis class (oxyplot.core\2.1.0\lib\netstandard2.0\OxyPlot.dll).

This is the corresponding code from my Theming sample (currently line 180):
axis.TicklineColor = OxyColors.DimGray;
axis.AxislineColor = OxyColors.Red; // Doesn't seem to work.

Indeed fixed the Contour series, but now the PieChart has an issue:

Thanks for the info, I'll see what I can do tomorrow.

[VisualMelon]

The default for AxislineStyle is LineStyle.None: you need to set that to e.g. AxislineStyle = LineStyle.Solid if you set the AxisLineColor also (which by default is black).

See for example https://github.com/oxyplot/oxyplot/blob/develop/Source/Examples/ExampleLibrary/Axes/AxisExamples.cs#L196

This means that the behavior is as intended, so the issue may be closed. Sorry to have bothered you with this one, @HavenDV.

Indeed fixed the Contour series, but now the PieChart has an issue:

Pie issue is a regression caused by the recent application of the PolyLineSegment workaround oxyplot/oxyplot#1848
I will investigate whether it is possible to solve all the problems at the same time.

[HavenDV]

I reverted the PolyLineSegment fix, Pie should work correctly. But the issue shown here - oxyplot/oxyplot#1848 will come back
But there the main reason is problems on the WinUI side - microsoft/microsoft-ui-xaml#6716
