   I experienced the same issue
   It seems like plplot dlls and fonts are not being loaded correctly in the NativeHelper.cs:

      // The NuGet package ships with the PLplot DLLs and supporting font and
      // color map files. These files get installed into the directory "plplot", 
      // either relative to the application main executable (if published),
      // or are located in the "runtimes/win-x64/native" folder of the NuGet package.
      // For PLplot to find its support files, the environment variable 
      // PLPLOT_LIB must be set accordingly.                
      string[] supPaths = {
      	Path.Combine(libDir, "plplot"), 
      	Path.Combine(libDir, "..", "..", "runtimes", "win-x64", "native", "plplot") 
      };
      string supPath = supPaths.FirstOrDefault(p => Directory.Exists(p));
      if (supPath != null) {                   
      	_putenv_s("PLPLOT_LIB", supPath);
      } else {
      	throw new InvalidOperationException($"Cannot find support PLplot support files in {supPaths}.");
      }

   This was looking in the directories:
   {NugetPath}\plplot and
   {NugetPath}\..\..\runtimes\win-x64\native\plplot

   Or when compiling locally
   {ProjectPathBinDirectory}\plplot and
   {ProjectPathBinDirectory}\..\..\runtimes\win-x64\native\plplot

   supPath would always be null and therefore throw exception.

   To resolve it locally, I changed the second supPath location to

      Path.Combine(libDir, "runtimes", "win-x64", "native", "plplot")
