SphericalProjAxes
(ProjClass, *args, **kwds)¶ Define a special Axes to take care of spherical projection.
Parameters: projection : a SphericalProj class or a class derived from it.
type of projection
rot : list or string
define rotation. See rotator.
coord : list or string
define coordinate system. See rotator.
coordprec : number of digit after floating point for coordinates display.
format : format string for value display.
Notes
Other keywords from Axes (see Axes).
Methods
delgraticules
()Delete all graticules previously created on the Axes. format_coord
(x, y)Format the coordinate for display in status bar. get_lonlat
(x, y)Get the coordinate in the coord system of the image, in lon/lat in deg. get_meridian_interval
(vx[, vy, vz])Get the min and max value of phi of the meridians to cover the field of view. get_parallel_interval
(vx[, vy, vz])Get the min and max value of theta of the parallel to cover the field of view. get_value
(x, y)Get the value of the map at position x,y graticule
([dpar, dmer, coord, local, verbose])Draw a graticule. projmap
(map, vec2pix_func[, vmin, vmax, ...])Project a map on the SphericalProjAxes. projplot
(*args, **kwds)projplot is a wrapper around matplotlib.Axes.plot()
to take into account theprojscatter
(theta[, phi])Projscatter is a wrapper around matplotlib.Axes.scatter()
to take into account the spherical projection.projtext
(theta, phi, s, **kwds)Projtext is a wrapper around matplotlib.Axes.text()
to take into account the spherical projection.set_coordprec
(n)Set the number of digits after floating point for coord display. set_format
(f)Set the format string for value display
