Question about the comma in palettes setting.

[himcraft]

Hi all,

Sorry for the dumb question, but when I tried to reproduce the results in the document section about palettes, I noticed that when I typed without the last comma as:

Axis(f[2, 1],
    title = "Custom cycle palette",
    palette = (patchcolor = [:red, :green, :blue, :yellow, :orange, :pink]))

instead of the original code given in the doc:

Axis(f[2, 1],
    title = "Custom cycle palette",
    palette = (patchcolor = [:red, :green, :blue, :yellow, :orange, :pink],))

It threw an error MethodError: no method matching iterate(::Symbol).

Can someone please explain to me the usage of the last comma? Thanks a lot!

That's because (x=2) is not (; x=2) or (x=2,) ;) The latter create a named tuple, while the first one just wraps it in brackets ;)

I got. Thank you for the example. :)
