Do you want you figure width to be exactly 3 inch? Otherwise, I wonder
why bbox_inches="tight" does not work.
My recommendation is
1) create a figure with high enough height.
2) adjust subplot parameters either manually or using the method
described in the FAQ.
3) call savefig with tight bbox option.
If you want your figure width to be exactly 3 inch, try something like below
fig = figure(1, figsize=(3,7))
ax = subplot(111)
ax.set_aspect(1)
def get_tightbbox(renderer, fig=fig):
from matplotlib.figure import Figure
from matplotlib.transforms import Bbox
bbox = Figure.get_tightbbox(fig, renderer)
w, h = fig.get_size_inches()
x1, y1, x2, y2 = bbox.extents
return Bbox.from_extents(0, y1, w, y2)
fig.get_tightbbox = get_tightbbox
savefig("a.png", bbox_inches="tight")
