Lilaq: Is it possible to number contour lines?

Hello,

Quick question about using the contour plot for the lilaq package. Is it possible to number the contour lines like it is in maps?

If no, is there a good-enough workaround?

#align(center, {
  let x = lq.linspace(-1.5,2.0)
  let y = lq.linspace(-0.5,3.0)
  lq.diagram(
    lq.contour(
      x,y,
      (x, y) => (calc.pow((1 - x), 2) + 100 * calc.pow(y - calc.pow(x,2), 2)),
      map: lq.color.map.plasma,
      max: 300,
      min: 10,
      levels: (800,600, 400, 200,100, 50, 10)
    )
  )
})

As reference what I’m trying to achieve (just the contour numbers, not the axis spacing nor the plotted line and red dot):

Hi @Electron_Wizard !

I’m sorry to say that this is not yet implemented for contour (it’s also not very easy). But I anticipate to change this some time.

For now, you could add the numbers yourself with lq.place (optionally with a white background to “erase” the contour line below). Of course this needs some manual placement …

That makes sense, I’ve also thought that it might be out of scope. If I have time (not until next week :) ), I might be able to create an example!
