Answering my own question a few months later... I've found an excellent example of good, easy animation in Julia, using PyPlot in a more pythonic way. It's the code posted at the bottom of this short discussion.
https://github.com/JuliaLang/IJulia.jl/issues/107 This is what I've been looking for for quite some time, and I'm quite excited :) Tom On Saturday, 20 December 2014 14:21:52 UTC+10, Thomas Moore wrote: > > I want to run a very simple animation using PyPlot: I use a for loop to > cycle through many different pieces of data, and in each iteration I clear > a plot, plot a new figure, and pause for, say, 0.01 seconds.
