matplotlib.patches.StepPatch

class matplotlib.patches.StepPatch(values, edges, *, orientation='vertical', baseline=0, **kwargs)

Bases: PathPatch

A path patch describing a stepwise constant function.

By default, the path is not closed and starts and stops at baseline value.

Parameters:

valuesarray-like

The step heights.

edgesarray-like

The edge positions, with len(edges) == len(vals) + 1, between which the curve takes on vals values.

orientation{'vertical', 'horizontal'}, default: 'vertical'

The direction of the steps. Vertical means that values are along the y-axis, and edges are along the x-axis.

baselinefloat, array-like or None, default: 0

The bottom value of the bounding edges or when fill=True, position of lower edge. If fill is True or an array is passed to baseline, a closed path is drawn.

**kwargs

capstyle	CapStyle or {'butt', 'projecting', 'round'}
clip_box	BboxBase or None
clip_on	bool

color	color
edgecolor or ec	color or None
edgegapcolor	color or None
facecolor or fc	color or None

get_data()

Get StepPatch values, edges and baseline as namedtuple.

Set multiple properties at once.

a.set(a=A, b=B, c=C)

is equivalent to

a.set_a(A)
a.set_b(B)
a.set_c(C)

In addition to the full property names, aliases are also supported, e.g. set(lw=2) is equivalent to set(linewidth=2), but it is an error to pass both simultaneously.

The order of the individual setter calls matches the order of parameters in set(). However, most properties do not depend on each other so that order is rarely relevant.
