    Eventually start the QApplication or only make a plot

    Parameters
    ----------
    %(make_plot.parameters)s
    backend: None or str
        The backend to use. By default, the ``'gui.backend'`` key in the
        :attr:`~psyplot_gui.config.rcsetup.rcParams` dictionary is used.
        Otherwise it can be None to use the standard matplotlib backend or a
        string identifying the backend
    new_instance: bool
        If True/set and the `output` parameter is not set, a new application is
        created
    rc_gui_file: str
        The path to a yaml configuration file that can be used to update  the
        :attr:`~psyplot_gui.config.rcsetup.rcParams`
    include_plugins: list of str
        The plugin widget to include. Can be either None to load all that are
        not explicitly excluded by `exclude_plugins` or a list of
        plugins to include. List items can be either module names, plugin
        names or the module name and widget via ``'<module_name>:<widget>'``
    exclude_plugins: list of str
        The plugin widgets to exclude. Can be either ``'all'`` to exclude
        all plugins or a list like in `include_plugins`.
    offline: bool
        If True/set, psyplot will be started in offline mode without
        intersphinx and remote access for the help explorer
    pwd: str
        The path to the working directory to use. Note if you do not provide
        any `fnames` or `project`, but set the `pwd`, it will switch the
        `pwd` of the current GUI.
    script: str
        The path to a python script that shall be run in the GUI. If the GUI
        is already running, the commands will be executed in this GUI.
    command: str
        Python commands that shall be run in the GUI. If the GUI is already
        running, the commands will be executed in this GUI
    use_all: bool
        If True, use all variables. Note that this is the default if the
        `output` is specified and not `name`
    exec_: bool
        If True, the main loop is entered.
    callback: str
        A unique identifier for the method that should be used if psyplot is
        already running. Set this parameter to None to avoid sending
    opengl_implementation: {'software', 'desktop', 'gles', 'automatic'}
        OpenGL implementation to pass to Qt. Possible options are
        'software', 'desktop', 'gles' and 'automatic' (which let's PyQt
        decide).
    webengineview: bool
        If True (default), use an HTML help widget. This might not be available
        for all builds of PyQt5 under all circumstances. If not set, the
        rcParams key ``'help_explorer.use_webengineview'`` is used.

    Parameters
    ----------
    %(make_plot.parameters)s
    backend: None or str
        The backend to use. By default, the ``'gui.backend'`` key in the
        :attr:`~psyplot_gui.config.rcsetup.rcParams` dictionary is used.
        Otherwise it can be None to use the standard matplotlib backend or a
        string identifying the backend
    new_instance: bool
        If True/set and the `output` parameter is not set, a new application is
        created
    rc_gui_file: str
        The path to a yaml configuration file that can be used to update  the
        :attr:`~psyplot_gui.config.rcsetup.rcParams`
    include_plugins: list of str
        The plugin widget to include. Can be either None to load all that are
        not explicitly excluded by `exclude_plugins` or a list of
        plugins to include. List items can be either module names, plugin
        names or the module name and widget via ``'<module_name>:<widget>'``
    exclude_plugins: list of str
        The plugin widgets to exclude. Can be either ``'all'`` to exclude
        all plugins or a list like in `include_plugins`.
    offline: bool
        If True/set, psyplot will be started in offline mode without
        intersphinx and remote access for the help explorer
    pwd: str
        The path to the working directory to use. Note if you do not provide
        any `fnames` or `project`, but set the `pwd`, it will switch the
        `pwd` of the current GUI.
    script: str
        The path to a python script that shall be run in the GUI. If the GUI
        is already running, the commands will be executed in this GUI.
    command: str
        Python commands that shall be run in the GUI. If the GUI is already
        running, the commands will be executed in this GUI
    use_all: bool
        If True, use all variables. Note that this is the default if the
        `output` is specified and not `name`
    exec_: bool
        If True, the main loop is entered.
    callback: str
        A unique identifier for the method that should be used if psyplot is
        already running. Set this parameter to None to avoid sending

    Returns
    -------
    None or :class:`psyplot_gui.main.MainWindow`
        ``None`` if `exec_` is True, otherwise the created
        :class:`~psyplot_gui.main.MainWindow` instance
