ScottPlot Dependencies

Adding the ScottPlot NuGet package to a .NET project typically brings all the dependencies it needs to run. In some cases additional steps need to be taken for apps that use ScottPlot to run smoothly.

SkiaSharp Native Assets for Linux

Non-Windows users may need to add the SkiaSharp.NativeAssets.Linux.NoDependencies NuGet package to projects that use ScottPlot to resolve the following errors:

System.DllNotFoundException: Unable to load shared library 'libSkiaSharp' or one of its dependencies

libSkiaSharp.so: cannot open shared object file

Font Rendering Issues

Non-Windows users may need to install system packages to fix font issues (e.g., characters are blank or appear as squares or rectangles):

apt-get update
apt-get install -y libfreetype6
apt-get install -y libfontconfig1
apt-get install -y fontconfig

If no characters render at all, it may be because the default font was incorrectly detected. Users may correct this issue by specifying the name of an installed font or by using a font contained in a .ttf file, as demonstrated in the ScottPlot 5 Cookbook.

ScottPlot 4 Warning CA1416

ScottPlot 4 users may encounter warning CA1416 because cross-platform support for System.Drawing was dropped in .NET 6. To resolve this issue, edit your .csproj file to target .net6.0-windows so your app only attempts to build for Windows.

Warning	CA1416 This call site is reachable on all platforms. 
'FormsPlot.Plot' is only supported on: 'Windows' 7.0 and later.

Users wishing to create cross-platform apps should use ScottPlot 5 which does not have this limitation.

ScottPlot 4 on Linux or MacOS

Non-Windows users may need to install libgdiplus using one of the following commands:

apt-get install -y libgdiplus

brew install mono-libgdiplus
