matplotlib基础——add_subplot()

add_subplot(*args, **kwargs)

Add a subplot.

Examples:

fig.add_subplot(111)

# equivalent but more general
fig.add_subplot(1,1,1)

# add subplot with red background
fig.add_subplot(212, facecolor='r')

# add a polar subplot
fig.add_subplot(111, projection='polar')

# add Subplot instance sub
fig.add_subplot(sub)

kwargs are legal Axes kwargs plus projection, which chooses a projection type for the axes. (For backward compatibility, polar=True may also be provided, which is equivalent to projection=’polar’). Valid values for projection are: [‘aitoff’, ‘hammer’, ‘lambert’, ‘mollweide’, ‘polar’, ‘rectilinear’]. Some of these projections support additional kwargs, which may be provided to add_axes().

The Axes instance will be returned.

If the figure already has a subplot with key (args, kwargs) then it will simply make that subplot current and return it.
