If you use a simple plot within a window, which you can resize to a minimum this leads an assertion error: "Height must be larger than 0 ..." Try this program:
<Window x:Class="BugReport.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:oxy="clr-namespace:OxyPlot.Wpf;assembly=OxyPlot.Wpf"
Title="Test Window">
<Grid>
<oxy:Plot Title="Test plot">
</oxy:Plot>
</Grid>
</Window>
Comments: Should be closed.
