healpy.projaxes.GnomonicAxes.projscatter¶
- GnomonicAxes.projscatter(theta, phi=None, *args, **kwds)¶
Projscatter is a wrapper around matplotlib.Axes.scatter() to take into account the spherical projection.
You can call this function as:
projscatter(theta, phi) # plot points at coord (theta, phi) projplot(thetaphi) # plot points at coord (thetaphi[0], thetaphi[1])
Parameters: theta, phi : float, array-like
Coordinates of point to plot. Can be put into one 2-d array, first line is then theta and second line is phi. See lonlat parameter for unit.
lonlat : bool, optional
If True, theta and phi are interpreted as longitude and latitude in degree, otherwise, as colatitude and longitude in radian
coord : {‘E’, ‘G’, ‘C’, None}, optional
The coordinate system of the points, only used if the coordinate coordinate system of the axes has been defined and in this case, a rotation is performed
rot : None or sequence, optional
rotation to be applied =(lon, lat, psi) : lon, lat will be position of the new Z axis, and psi is rotation around this axis, all in degree. if None, no rotation is performed
direct : bool, optional
if True, the rotation to center the projection is not taken into account
Notes
Other keywords are passed to matplotlib.Axes.plot().
