Axes.margins(*args, **kw)¶Set or retrieve autoscaling margins.
signatures:
margins()
returns xmargin, ymargin
margins(margin)
margins(xmargin, ymargin)
margins(x=xmargin, y=ymargin)
margins(..., tight=False)
All three forms above set the xmargin and ymargin parameters.
All keyword parameters are optional. A single argument
specifies both xmargin and ymargin. 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 will preserve the previous setting.
Specifying any margin changes only the autoscaling; for example, if xmargin is not None, then xmargin times the X data interval will be added to each end of that interval before it is used in autoscaling.
