All input parameters must be floats greater than -0.5. Passing both
positional and keyword arguments is invalid and will raise a TypeError.
If no arguments (positional or otherwise) are provided, the current
margins will remain unchanged and simply be returned.
If a single positional argument is provided, it specifies
both margins of the x-axis and y-axis limits. If two
positional arguments are provided, they will be interpreted
as xmargin, ymargin. If setting the margin on a single
axis is desired, use the keyword arguments described below.
x, yfloat, optional
Specific margin values for the x-axis and y-axis,
respectively. These cannot be used with positional
arguments, but can be used individually to alter on e.g.,
only the y-axis.
tightbool or None, default: True
The tight parameter is passed to autoscale_view,
which is executed after a margin is changed; the default
here is True, on the assumption that when margins are
specified, no additional padding to match tick marks is
usually desired. Setting tight to None preserves
the previous setting.
If a previously used Axes method such as pcolor() has set
use_sticky_edges to True, only the limits not set by
the "sticky artists" will be modified. To force all
margins to be set, set use_sticky_edges to False
before calling margins().
