I would like to make a scatter plot, much like those in blog.zacharyabel.com/2012/06/putting-the-why-in-wythoff/ and blog.zacharyabel.com/2012/04/wythoffs-game-red-or-blue/ regarding Wythoff's Game. Right now my best approximation is using scatter_plot and gridlines='minor', but it's not quite what I'm looking for. Does anyone know if it's possible in Sage?
