I have been trying to plot spheres but there are cases when the aspect_ratio=:equal command just doesn't work, example:

using Plots
function plotCC(pos, rad, n = 16) # Function to spheres
    u = collect(range(0,stop=2,length=n));
    v = collect(range(0,stop=1,length=n));
    x = pos * ones(n) * ones(n)' + rad * cospi.(u) * sinpi.(v)';
    y = rad * sinpi.(u) * sinpi.(v)';
    z = rad * repeat(cospi.(v)',outer=[n, 1])
    surface!(x,y,z, aspect_ratio=:equal)
end
plotlyjs(dpi=1500)
x = -15:0.1:10
y = -2:0.1:2
plot(x,y,(x,y) -> sin(x)*cos(y)*0.5, linetype=:surface, aspect_ratio=:equal, color=:magma)
plotCC(1,2,32)
plotCC(-15,3,32)
gui()

which will give me this:
no_AspectRatio

but if I plot the second sphere with rad=5 then this is the result:
AspectRatio

Is this some kind of limitation of Plots.jl ? It looks like it is deciding not to do aspect_ratio=:equal just because the data is too stretched, but I need to plot it with equally scaled axis (or the spheres won't look like it). Any advise?

This is a huge issue IMO and largely ignored by many plotting libraries. Without proper equal aspect ratio figures, many use cases revolving around movement through three dimensional space lose all physical intuition. Has there been any progress on this?

I know this is something that is not available in matplotlib, plotly, etc. natively. Is there a way for us to get around that limitation?

Thanks @JMmontilla for laying out this issue in detail. Along with @rjpower4 I'd like to know if there has been any progress here. I've been getting into Julia recently for physical applications and having equal axis scaling in all three dimensions is very important to me.

I'm using the Plots Plotly backend for its interactivity and ability to render multiple plots in-browser, and I'm interested in either a native feature addition or some sort of workaround I can code up. Any advice is appreciated. Thanks!

aspect_ratio

I have the same issue (see above). Has it been solved?
