Méthode matplotlib.figure.Axes.step

Signature de la méthode step

def step(self, x, y, *args, where='pre', data=None, **kwargs) 

Description

help(Axes.step)

Make a step plot.

Call signatures::

    step(x, y, [fmt], *, data=None, where='pre', **kwargs)
    step(x, y, [fmt], x2, y2, [fmt2], ..., *, where='pre', **kwargs)

This is just a thin wrapper around `.plot` which changes some
formatting options. Most of the concepts and parameters of plot can be
used here as well.

.. note::

    This method uses a standard plot with a step drawstyle: The *x*
    values are the reference positions and steps extend left/right/both
    directions depending on *where*.

    For the common case where you know the values and edges of the
    steps, use `~.Axes.stairs` instead.

Parameters
----------
x : array-like
    1D sequence of x positions. It is assumed, but not checked, that
    it is uniformly increasing.

y : array-like
    1D sequence of y levels.

fmt : str, optional
    A format string, e.g. 'g' for a green line. See `.plot` for a more
    detailed description.

    Note: While full format strings are accepted, it is recommended to
    only specify the color. Line styles are currently ignored (use
    the keyword argument *linestyle* instead). Markers are accepted
    and plotted on the given positions, however, this is a rarely
    needed feature for step plots.

where : {'pre', 'post', 'mid'}, default: 'pre'
    Define where the steps should be placed:

    - 'pre': The y value is continued constantly to the left from
      every *x* position, i.e. the interval ``(x[i-1], x[i]]`` has the
      value ``y[i]``.
    - 'post': The y value is continued constantly to the right from
      every *x* position, i.e. the interval ``[x[i], x[i+1])`` has the
      value ``y[i]``.
    - 'mid': Steps occur half-way between the *x* positions.

data : indexable object, optional
    An object with labelled data. If given, provide the label names to
    plot in *x* and *y*.

**kwargs
    Additional parameters are the same as those for `.plot`.

Returns
-------
list of `.Line2D`
    Objects representing the plotted data.
