Installed pyQt etc. via synaptic, then Qwt.jl cloned from here, when using i get:

You missed this step: Add the Qwt/src/python directory to your PYTHONPATH environment variable.
However, I should probably just add this to the julia environment variables programatically. I'll wait to close the issue until I do that.
I tend to disagree...

It might be a path problem but your change doesn't help.
Ok. Maybe PyCall has its own copy of ENV? I'll have to check when I get home. Either way you can still set your PYTHONPATH yourself.

Reopening to investigate. I suspect this may be related to PyCall precompilation, but I need to look deeper.
Seems to work for me now without a PYTHONPATH set. I also tested with a clean cache and using PyCall before using Qwt, so I expect this should work in all cases. Can you try it out?

I pushed to master... please try again. Thanks for sticking with me... I clearly haven't had people use this from enough environments.
Works.
For platform specific notes, if you collect this:
I'm running an out-of-the-box Ubuntu14.04, installed python 2.7.6 and python-qwt5-qt4 with synaptic. My julia build is local.
I had some problems running other qt5 SW on my desktop as a use a non-compositing WM. The qt4 here seems fine.
One comment on qwt itself: After all the talk about plotting speed and interaction this looks a little bit disappointing; Non-antialiased line drawing (also the grids), panning only the current picture.
Thanks... glad you got it working.
As for your comments... I agree that it's not blazing fast... we did some tests a while ago and time-to-plot was similar in PyPlot and Qwt (of course the Plots.jl api will allow me to do some nice automated benchmark comparisons in the future). I also agree that if you want smooth, production-quality plots that something like Gadfly might be nicer.
I like Qwt because it's fast enough (usually), has most of the interaction I ever need (pan/zoom/toggle) and is pretty space efficient, with a legend that doesn't block the series, subplots with sliders between them, etc. If there's something specific that would make it better, it's possible I just don't have a feature turned on, so let me know (for example, I have a "fancy plot" sitting unused right now that has good handling of dates, linked axes between subplots, etc. If people start using Qwt as a Plots.jl backend, I may work on making that available.)
works as expected, closed.
