The contourf function behaves very strangely when plotting data points on a logarithmic grid. Supplying the x- and y-positions of the data points and setting scale=:log10 completely messes up the plot. Here is a minimal example:
using Plots
xs = [10^i for i in range(-5, 5, length=50)]
data = [log(i*j) for i in xs, j in xs]
p1 = contourf(data, title="actual data")
p2 = contourf(xs, xs, data, scale=:log10, title="messed up data")
plot(p1, p2)
Am I am not sure if I am doing something wrong or if there is an issue with contourf. Thanks for help!
