at(x=None, y=None, phi=None, deg=None, rad=None, along=None, notransform=False)
at(x, y) specifies that future text will be placed at data location (x,y) Optional arguments:
deg - text will be rotated counterclockwise by deg degrees.
rad - text will be rotated counterclockwise by rad radians.
phi - specifies that the text will be rotated clockwise by phi radians (deprecated).
along - must be a tuple (dx,dy), meaning that the text will be rotated s.t. the baseline points in the data direction (dx,dy).
x may also be one of 'left,' 'right,' 'center,' 'abs,' 'absolute.' y may also be one of 'top,' 'bottom,' 'middle,' 'abs,' 'absolute.' If x and/or y is omitted, placements reverts to absolute in those dimensions.
