                       Tableau tableau)
        Construct a frame associated with the specified Ptolemy II model or object. After constructing this, it is necessary to call setVisible(true) to make the frame appear. This is typically done by calling show() on the controlling tableau. This constructor results in a graph frame that obtains its library either from the model (if it has one) or the default library defined in the configuration.
        Parameters:
        entity - The model or object to put in this frame.
        tableau - The tableau responsible for this frame.

        public BasicGraphFrame​(NamedObj entity,
                       Tableau tableau,
                       LibraryAttribute defaultLibrary)
        Construct a frame associated with the specified Ptolemy II model. After constructing this, it is necessary to call setVisible(true) to make the frame appear. This is typically done by calling show() on the controlling tableau. This constructor results in a graph frame that obtains its library either from the model (if it has one), or the defaultLibrary argument (if it is non-null), or the default library defined in the configuration.
        Parameters:
        entity - The model or object to put in this frame.
        tableau - The tableau responsible for this frame.
        defaultLibrary - An attribute specifying the default library to use if the model does not have a library. The defaultLibrary attribute is only read if the model does not have a LibraryAttribute with the name "_library", or if the LibraryAttribute cannot be read.
        See Also:
        Tableau.show()
