Manually created PlotView does not appear

[lukaszksoll]

Hi! I have a problem after OxyPlot update from 2.0.0 to 2.1.0. Currently I cannot display a manually created (in code-behind) PlotView within the tooltip of the canvas. I tried to reproduce it on simpler example and it seems to behave the same.

In the following example tooltip is always empty. It contains proper size control, but there is no chart on the view. Within the comments you can find some code that works, but without tooltip.

When I'm trying to do this implementing PlotView in xaml code via VM - it works.

MainWindow.xaml.cs:

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

            var plotModel = new PlotModel
            {
                Title = "Long axis titles (clipped at 100%)",
                Series = { new FunctionSeries(Math.Cos, 0, 10, 400) },
            };
            var plotView = new PlotView
            {
                Model = plotModel,
                Width = 400,
                Height = 400,
            };

            var tooltip = new ToolTip { Content = plotView };

            // It works
            //var grid = new Grid()
            //{
            //    Children = { plotView }
            //};
            //Main.Content = grid;

            // It doesn't work
            var grid = new Grid
            {
                Width = 400,
                Height = 500,
                Background = Brushes.Red,
                ToolTip = tooltip,
            };

            grid.ToolTipOpening += (s, args) => plotView.InvalidatePlot();
            Main.Content = grid;


            plotView.InvalidatePlot();
        }
    }

MainWindow.xaml:

<Window x:Class="WpfApp1.MainWindow"
       xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

       mc:Ignorable="d"
       Title="MainWindow" Height="450" Width="800" x:Name="Main">

</Window>

.NET version: 4.8/6.0

Thank you for your help!

Sounds like #1796

Are you able to test a pre-release version?

[lukaszksoll]

Yes, you're right. That's the problem. Are there any plans to release a fix for that?

[VisualMelon]

This should be fixed in the 2.1.2 release. Closing, but feel free to re-open if there is still a problem.
