Classe « Axes »

Méthode matplotlib.figure.Axes.axline

Signature de la méthode axline

def axline(self, xy1, xy2=None, *, slope=None, **kwargs) 

Description

axline.__doc__

Add an infinitely long straight line.

The line can be defined either by two points *xy1* and *xy2*, or
by one point *xy1* and a *slope*.

This draws a straight line "on the screen", regardless of the x and y
scales, and is thus also suitable for drawing exponential decays in
semilog plots, power laws in loglog plots, etc. However, *slope*
should only be used with linear scales; It has no clear meaning for
all other scales, and thus the behavior is undefined. Please specify
the line using the points *xy1*, *xy2* for non-linear scales.

The *transform* keyword argument only applies to the points *xy1*,
*xy2*. The *slope* (if given) is always in data coordinates. This can
be used e.g. with ``ax.transAxes`` for drawing grid lines with a fixed
slope.

Parameters
----------
xy1, xy2 : (float, float)
    Points for the line to pass through.
    Either *xy2* or *slope* has to be given.
slope : float, optional
    The slope of the line. Either *xy2* or *slope* has to be given.
