Is it really that hard?
def compass( theta, r, **kwargs ):
matplotlib.pyplot.polar( math.pi/2 - theta, r, **kwargs )
or, to handle lists of points:
def compass( theta, r, **kwargs ):
d90 = math.pi/2
if type(theta) == list:
rotate = [d90 - k for k in theta]
return matplotlib.pyplot.polar( rotate, r, **kwargs )
else:
return matplotlib.pyplot.polar( d90 - theta, r, **kwargs )
