I made a PR (Add support for the GR backend #207
<https://github.com/stevengj/PyPlot.jl/pull/207>) to enable GR support for
the PyPlot library. It would be nice if the changes could be merged.
I don't know, why showing the plot should freeze everything else.
Changing the backend to GR did speed-up the following animation example by
a factor > 3:
ENV["MPLBACKEND"] = "module://gr.matplotlib.backend_gr"
import PyPlot
x = collect(0:0.01:2*pi)
line, = PyPlot.plot(x, sin(x))
for i = 1:200
line[:set_ydata](sin(x + i / 10.0))
PyPlot.draw()
PyPlot.pause(0.0001)
end
Thanks in advance,
Josef
