Editing titles after creating a Makie plot

Specific Domains Visualization
1

I’m customizing Makie.plot to edit axis properties due to Accessing axis in Makie plot recipes. My function looks something like this:

function foo(fig = Makie.Figure())
  axes = [Makie.Axis(fig[i,j]) for j in 1:3, i in 1:2]
  for (i, ax) in enumerate(axes)
    Makie.scatter!(ax, randn(10))
    ax.title = "Plot number $i"
  end
  fig
end

I’d like users to be able to edit the plot afterwards (like adding or remove titles). Is there a recommended way to do this?

I wasn’t sure how to recover axes from the return argument fig. I thought maybe I should return a Makie.FigureAxisPlot instead so that there is a way to access the axis, but I wasn’t sure how to specify the plot field.

No recommended way, you can return the axes in a tuple with the Figure if they’re important, otherwise you could theoretically still get at them via the content function for example.

Thanks for the tip on content. However, fig.content is a vector instead of a matrix, and I’d like to pass the latter to users if possible since the layout is more intuitive.

If I return fig, axes in a tuple, the plot doesn’t pop up. I’d like to be able to call foo() to have the plot appear, but also return a configurable plot object. That’s why I was thinking of returning FigureAxisPlot - it returns axis information but also makes the plot pop up. However, I’m not sure what to provide for the plot field here.

This seems to work:

using GLMakie

function foo(fig = Makie.Figure())
    axes = [Makie.Axis(fig[i,j]) for j in 1:3, i in 1:2]
    for (i, ax) in enumerate(axes)
      Makie.scatter!(ax, randn(10))
      ax.title = "Plot number $i"
    end
    display(fig)
    fig, axes
end

fig, axesv = foo()

axesv[1].title = "Hello No.1 !"
axesv[5].title = "Hello No.5 !"

Yes, but it then requires typing fig to actually display the plot. I’d like to have foo() both display the figure, and also return axis information.

What Makie command does typing “fig” actually call to show the figure? I think I could wrap fig and axes in a custom type and overload the “show figure” command.

Just add: display(fig) before returning the axes ?

NB: edited code above accordingly

I didn’t know that worked…thanks!
