Displaying multiple plots at the same time

Hi all, I was trying to plot multiple Gadfly plots and display them in two separate figures. However, only the second plot was displayed.

function draw_stuff()
  Gadfly.plot(x=[1,1,2,2],[3,4,5,6],Geom.violin)
  Gadfly.plot(x=[1,1,2,2],[3,4,5,6],Geom.line)
end

Do I have to explicitly put each plot in display() or is there something that I’m missing when I called the Gadfly plots?

Yes.

plot doesn’t display a plot by itself, it returns a Plot object. Those Plot objects automatically get displayed if they’re the return value of a REPL line or notebook cell, but not otherwise. Here, I’m assuming you’re calling draw_stuff on the REPL or a notebook, which will return the second line’s Plot object, so that’ll be the only one displayed.

You can either display(plot(...)) or add show = true as an argument to the plot calls: plot(..., show = true).

(All of the above is based on the general Plots.jl library - I’m assuming Gadfly also provides the same interface, at least with regard to simple things like this. )

Use display(plot(...)), or possibly hstack, vstack or gridstack several plots (lots of examples in the Gadfly Gallery).

Thank you for the explanation!

Thanks for the suggestion! However, I was looking to plot in separate figures rather than in subplots, which seems to be what the stack functions do.
