There are several ways.
For PyPlot plots, you can just use the savefig command, e.g.
plot(x,y)
savefig("myplot.eps")
where for publication quality you generally want to save to a vector format
like EPS, PDF, or SVG.
Given a figure object (returned e.g. by gcf() in PyPlot), you can also use
writemime to write it to one of these formats, e.g:
plot(x,y)
open("myplot.pdf", "w") do io
writemime(io, "image/pdf", gcf())
end
This is less convenient than savefig, but I mention it because most of the
other plotting packages for Julia also support writemime (since writemime
is also used to display their plots in Julia).
Finally, you can use IPython's powerful nbconvert tool
(http://ipython.org/ipython-doc/rel-1.0.0/interactive/nbconvert.html) to
convert a notebook, including figures, to a variety of formats for
publication. However, by default PyPlot only stores display-quality PNGs
in the notebook, so you have to enable SVG notebook output by
PyPlot.svg(true) first. See:
