World coordinates are the same as those in the WCS Transformation from pixel to world coordinates, where the This does not include the transData transformation Parameters frame WCS or Transform or str The frame parameter can have several possible types: See also _window_extent _tightbbox _window_extent get_transform ( frame ) ¶ Returns BboxBaseīounding box in figure pixel coordinates. The xlabel, or the y-extent of the ylabel.

Reset the current Axes, to use a new WCS object.
Plot Sk圜oord or BaseCoordinateFrame objects onto the axes. Return a transform from the specified frame to display coordinates. Return the tight bounding box of the axes, including axis and their decorators (xlabel, title, etc).
