healpy.projaxes.GnomonicAxes¶
- class healpy.projaxes.GnomonicAxes(*args, **kwds)¶
Define a gnomonic Axes to handle gnomonic projection.
- Input:
- rot=, coord= : define rotation and coordinate system. See rotator.
- coordprec= : number of digit after floating point for coordinates display.
- format= : format string for value display.
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[, xsize, ysize, reso]) projplot(*args, **kwds) projplot is a wrapper around matplotlib.Axes.plot() to take into account the projscatter(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
