Thanks for the suggestion Ismael. Yeah, I originally came from the RStudio
world, so I was mirroring ctrl+enter from that world and personally have
never used ctrl+enter in sublime (really, the most useful command?!).

I'd really love to see more examples in the manual, like Processing does:

uses them?

Just starting taking a look at Julia. I have seen examples on how to send
a plot to a file. But I have not stumbled upon one example as yet to
export multiple plots to the same file, say pdf.
Can someone please point me in the right direction?

Steven,
Thanks for the reply, I'd definitely like to get something working for
plots. I just did a quick test, but I wasn't able to see an image/png tag
in display_data when I ran the following:
using Gadfly
plot(x=[1:10], y=[1:10], Geom.point)
Do I need to explicitly push the image/png mime typ
Yes, the manual is a bit sparing with examples. We definitely are getting
to the point where something more expansive with more examples is needed.

There's not a way to put them on separate pdf pages, but you can stack them
and output them to the same pdf like:
using Gadfly
x = [1,2,3]
plot1 = plot(x = x, y = x + 3)
plot2 = plot(x = x, y = 2 * x + 1)
draw(PDF("plotJ.pdf", 6inch, 6inch), vstack(plot1, plot2))

FYI, this claim about the safety of symbols is actually not true. You can
reassign the bindings of sym just as easily as you can reassign the bindings of
a variable bound to a.

This is obviously a useful thing that one might want to do, so it should
work, and you did exactly the right thing – complain! The squeaky wheel

Ouch!
In my opinion, this may be a major stumbling block for Julia adoption.
I, and I am sure many, find it typical routine to load data, crunch, make a
variety of graphical views (sometimes very many), export them to files in
an organized way for analysis and sharing a story line.

Awesome. Thanks Stefan.
Next time I'll take your advice and file an issue. I tend to be hesitant about
these things as I'm such a newbie at github and the like. Thanks for the
