This .NET class wraps the AcPlPlotFactory ObjectARX class. 

The PlotFactory class creates plot engines for use by applications. Only one engine can exist at a time, so applications should create engines just before they are needed and destroy them (by calling PlotEngine.destroy()) when they are no longer needed.
