matplotlib.axes.Axes.indicate_inset

Axes.indicate_inset(bounds=None, inset_ax=None, *, transform=None, facecolor='none', edgecolor='0.5', alpha=0.5, zorder=None, **kwargs)

Add an inset indicator to the Axes. This is a rectangle on the plot at the position indicated by bounds that optionally has lines that connect the rectangle to an inset Axes (Axes.inset_axes).

Parameters:

bounds[x0, y0, width, height], optional

Lower-left corner of rectangle to be marked, and its width and height. If not set, the bounds will be calculated from the data limits of inset_ax, which must be supplied.

inset_axAxes, optional

An optional inset Axes to draw connecting lines to. Two lines are drawn connecting the indicator box to the inset Axes on corners chosen so as to not overlap with the indicator box.

transformTransform

Transform for the rectangle coordinates. Defaults to ax.transAxes, i.e. the units of rect are in Axes-relative coordinates.

facecolorcolor, default: 'none'

Facecolor of the rectangle.

edgecolorcolor, default: '0.5'

Color of the rectangle and color of the connecting lines.

alphafloat or None, default: 0.5

Transparency of the rectangle and connector lines. If not None, this overrides any alpha value included in the facecolor and edgecolor parameters.

zorderfloat, default: 4.99

Drawing order of the rectangle and connector lines. The default, 4.99, is just below the default level of inset Axes.

**kwargs

Other keyword arguments are passed on to the Rectangle patch:

animated	bool
antialiased or aa	bool or None
bounds	(left, bottom, width, height)
capstyle	CapStyle or {'butt', 'projecting', 'round'}
clip_box	BboxBase or None
clip_on	bool
clip_path	Patch or (Path, Transform) or None
color	color
edgecolor or ec	color or None
facecolor or fc	color or None

hatch_linewidth	unknown
height	unknown
in_layout	bool
joinstyle	JoinStyle or {'miter', 'round', 'bevel'}
label	object
linestyle or ls	{'-', '--', '-.', ':', '', (offset, on-off-seq), ...}
linewidth or lw	float or None
mouseover	bool
path_effects	list of AbstractPathEffect
picker	None or bool or float or callable
rasterized	bool
sketch_params	(scale: float, length: float, randomness: float)
snap	bool or None
transform	Transform
url	str
visible	bool
width	unknown
x	unknown
xy	(float, float)
y	unknown
zorder	float

Returns:

inset_indicatorinset.InsetIndicator

An artist which contains

inset_indicator.rectangleRectangle

The indicator frame.

inset_indicator.connectors4-tuple of patches.ConnectionPatch

The four connector lines connecting to (lower_left, upper_left, lower_right upper_right) corners of inset_ax. Two lines are set with visibility to False, but the user can set the visibility to True if the automatic choice is not deemed correct.

Changed in version 3.10: Previously the rectangle and connectors tuple were returned.

Warning

This method is experimental as of 3.0, and the API may change.
