Projections are defined as `~.axes.Axes` subclasses. They include the following elements: - A transformation from data coordinates into display coordinates. - An inverse of that transformation. This is used, for example, to convert mouse positions from screen space back into data space. - Transformations for the gridlines, ticks and ticklabels. Custom projections will often need to place these elements in special locations, and Matplotlib has a facility to help with doing so. - Setting up default values (overriding `~.axes.Axes.cla`), since the defaults for a rectilinear Axes may not be appropriate. - Defining the shape of the Axes, for example, an elliptical Axes, that will be used to draw the background of the plot and for clipping any data elements. - Defining custom locators and formatters for the projection. For example, in a geographic projection, it may be more convenient to display the grid in degrees, even if the data is in radians. - Set up interactive panning and zooming. This is left as an "advanced" feature left to the reader, but there is an example of this for polar plots in `matplotlib.projections.polar`. - Any additional methods for additional convenience or features. Once the projection Axes is defined, it can be used in one of two ways: - By defining the class attribute ``name``, the projection Axes can be registered with `matplotlib.projections.register_projection` and subsequently simply invoked by name:: fig.add_subplot(projection="my_proj_name") - For more complex, parameterisable projections, a generic "projection" object may be defined which includes the method ``_as_mpl_axes``. ``_as_mpl_axes`` should take no arguments and return the projection's Axes subclass and a dictionary of additional arguments to pass to the subclass' ``__init__`` method. Subsequently a parameterised projection can be initialised with:: fig.add_subplot(projection=MyProjection(param1=param1_value)) where MyProjection is an object which implements a ``_as_mpl_axes`` method. A full-fledged and heavily annotated example is in :doc:`/gallery/misc/custom_projection`. The polar plot functionality in `matplotlib.projections.polar` may also be of interest. )axes _docstring) AitoffAxes HammerAxes LambertAxes MollweideAxes) PolarAxes)Axes3DNzUnable to import Axes3D.
