[julia-users] Re: Interactive Animated PyPlot in IJulia

[Steven G. Johnson]

PyPlot, like the Python package of the same name, plots as a side effect. You 
can use the withfig function to wrap PyPlot commands and make them functional 
(returning the figure object as the withfig return value rather than displaying 
it as a side effect). This allows Pyplot to be used with @manipulate, but 
should also work with other Reactive functions.
