Comment (by ppurka):
Here is a "minimal" (really???!!!) code to reproduce it in matplotlib
{{{
from matplotlib.figure import Figure
from matplotlib.ticker import NullLocator
from matplotlib.backends.backend_agg import FigureCanvasAgg
import matplotlib.lines as lines
figure=Figure()
subplot = figure.add_subplot(111)
subplot.add_line(lines.Line2D(range(10), range(10)))
subplot.spines['right'].set_visible(False)
subplot.spines['left'].set_position(('outward',10))
subplot.spines['top'].set_visible(False)
subplot.spines['bottom'].set_position(('outward',10))
subplot.xaxis.set_major_locator(NullLocator())
subplot.yaxis.set_major_locator(NullLocator())
figure.set_canvas(FigureCanvasAgg(figure))
figure.savefig('a.png', bbox_inches='tight', bbox_extra_artists=[])
}}}
Things which bring back the axes:
1. Set the `outward` parameter a bit less
{{{
subplot.spines['bottom'].set_position(('outward',7)) # just barely
subplot.spines['left'].set_position(('outward',7))
}}}
2. Either remove `bbox_inches='tight'` or `bbox_extra_artists=[]` from the
`savefig` command.
