Hello, I was trying to generate a stream plot using PythonPlot.jl like this example: Julia_Examples/pyplot_streamplot.jl at master · gizmaa/Julia_Examples · GitHub
However, I was encounter an error while running the following code. I would like to know how to correctly call streamplot() under PythonPlot.jl .
using PythonPlot
## This works
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")
gcf()
#---
minval = -3
maxval = 3
steps = 100
X = repeat(range(minval,stop=maxval,length=steps)',steps)
Y = repeat(range(minval,stop=maxval,length=steps),1,steps)
U = -1 .- X.^2 .+ Y
V = 1 .+ X .- Y.^2
speed = sqrt.(U.^2 .+ V.^2)
fig = figure("pyplot_streamplot",figsize=(10,10))
subplot(311)
streamplot(X,Y,U,V) ## This line gives error
Error message:
