AxesStack
[source]¶Bases: matplotlib.cbook.Stack
Specialization of the Stack
to handle all tracking of
Axes
in a Figure
.
This stack stores key, (ind, axes)
pairs, where:
- key should be a hash of the args and kwargs used in generating the Axes.
- ind is a serial number for tracking the order in which axes were added.
The AxesStack is a callable, where ax_stack()
returns
the current axes. Alternatively the current_key_axes()
will
return the current key and associated axes.
add
(self, key, a)[source]¶Add Axes a, with key key, to the stack, and return the stack.
If key is unhashable, replace it by a unique, arbitrary object.
If a is already on the stack, don't add it again, but return None.
current_key_axes
(self)[source]¶Return a tuple of (key, axes)
for the active axes.
If no axes exists on the stack, then returns (None, None)
.
