Dear all,  
How can I reduze the zscale in my plot?

```julia
using Plots
plotly()

f(x,y) = y < x ? cos(8x) + sin(8y) : NaN
x = LinRange(-2, 2, 100);
y = LinRange(-2, 2, 100);
surface(x, y, f,aspect_ratio = .3)

```

See the strange figure. Aspect ration reduces all dimensions…

Try playing with the `zlims` argument, for ex.: `surface(x, y, f, zlims=(-4,4))`

@angeloaliano1  
To customize both aspect ratio and plot aesthetics you can use PlotlyJS.jl:

```julia
using PlotlyJS
include("plotlyju.jl"); # style file: https://gist.github.com/empet/6b4f441ed96d724d67ff77f1fb8b0a79

f(x,y) = y < x ? cos(8x) + sin(8y) : NaN
xg = -2:0.02:2
z = [f.(x,y) for x in xg, y in xg];

trace = PlotlyJS.surface(x=xg, y =xg, z=z, 
                         colorbar_len=0.7)
pl = PlotlyJS.plot(trace, 
                   Layout(width=600, height=600,
                         scene_aspectratio=attr(x=1, y=1, z=0.5)), 
                   style=plotlyju)

```
