When trying to execute the example in the README: ``` using PyPlot x = range(0; stop=2*pi, length=1000); y = sin.(3 * x + 4 * cos.(2 * x)); plot(x, y, color="red", linewidth=2.0, linestyle="--") title("A sinusoidally modulated sinusoid") ``` I get the following error in `Julia 1.4.2` and `PyPlot v2.9.0` ``` MethodError: no method matching py_linestyle(::Symbol, ::String) ```
