yfloat, default: 0: y position in data coordinates of the horizontal line.
xminfloat, default: 0: Should be between 0 and 1, 0 being the far left of the plot, 1 the far right of the plot.
xmaxfloat, default: 1: Should be between 0 and 1, 0 being the far left of the plot, 1 the far right of the plot.

Returns:

Line2D

Other Parameters:

**kwargs

Valid keyword arguments are Line2D properties, with the exception of 'transform':
