- Plot Assistant
  Use the Plot Assistant to create plots from the various 2D and 3D OML plot types.
- Extension Manager
  Use the Extension Manager to create custom extensions, load extensions automatically, and add custom documentation for defined features.
- OML Functions in HyperWorks Products
  OML functions can be registered from the Compose graphical user interface or via a preference file and later opened in certain HyperWorks products.
- OML Libraries
  Additional libraries can be written in the C/C++ or Fortran language and interfaced with OML.
Reference Guides
Reference guides are available for functions and commands supported by OML, Tcl, and Python.

Assign Axes to GUIs

Create objects using Axes.

To create an axes object that generates a plot within a GUI, define an axes handle as follows. Run the example code, and notice that space is created for a plot.

f = figure();
ax = axes(f,'units','normalized','position',[0.1 0.1 0.5 0.5]);
