[julia-users] Interact + PyPlot: only update when releasing slider

[Andrei Berceanu]

I have some code along the lines of

f = figure()
@manipulate for α=1:0.1:3, β=1:0.1:3, γ=1:0.1:3; withfig(f) do
        y = fun(α,β,γ)
        PyPlot.plot(x, y)
    end
end

where fun is a *very slow* function to evaluate. Is there any way to tell 
@manipulate to update the resulting plot only after I release the sliders? 
Otherwise what I get is, I release them to the desised values and then have 
to wait ages for all the intermediate plots to be drawn.

Tnx!
