class mpl_toolkits.axes_grid1.inset_locator.InsetPosition(parent, lbwh)

Bases: object

An object for positioning an inset axes.

This is created by specifying the normalized coordinates in the axes, instead of the figure.

Parameters:

parent : matplotlib.axes.Axes

Axes to use for normalizing coordinates.

lbwh : iterable of four floats

The left edge, bottom edge, width, and height of the inset axes, in units of the normalized coordinate of the parent axes.

Examples

The following bounds the inset axes to a box with 20% of the parent axes’s height and 40% of the width. The size of the axes specified ([0, 0, 1, 1]) ensures that the axes completely fills the bounding box:

>>> parent_axes = plt.gca()
>>> ax_ins = plt.axes([0, 0, 1, 1])
>>> ip = InsetPosition(ax, [0.5, 0.1, 0.4, 0.2])
>>> ax_ins.set_axes_locator(ip)
mpl_toolkits.axes_grid1.inset_locator.inset_axes(parent_axes, width, height, loc=1, bbox_to_anchor=None, bbox_transform=None, axes_class=None, axes_kwargs=None, borderpad=0.5)

Create an inset axes with a given width and height.

Both sizes used can be specified either in inches or percentage of the parent axes.

Parameters:

parent_axes : matplotlib.axes.Axes

Axes to place the inset axes.

width, height : float or str

Size of the inset axes to create.

loc : int or string, optional, default to 1

Location to place the inset axes. The valid locations are:
