Signature de la méthode axhline

def axhline(self, y=0, xmin=0, xmax=1, **kwargs) 

Description

axhline.__doc__

Add a horizontal line across the axis.

Parameters
----------
y : float, default: 0
    y position in data coordinates of the horizontal line.

xmin : float, default: 0
    Should be between 0 and 1, 0 being the far left of the plot, 1 the
    far right of the plot.

xmax : float, default: 1
    Should be between 0 and 1, 0 being the far left of the plot, 1 the
    far right of the plot.

Returns
-------
`~matplotlib.lines.Line2D`

Examples
--------
* draw a thick red hline at 'y' = 0 that spans the xrange::

    >>> axhline(linewidth=4, color='r')

* draw a default hline at 'y' = 1 that spans the xrange::

    >>> axhline(y=1)

* draw a default hline at 'y' = .5 that spans the middle half of
  the xrange::

    >>> axhline(y=.5, xmin=0.25, xmax=0.75)
