Specify heights in Poset.plot

edit

Hi, I'm relatively new to Python and SAGE so please make it simple :)

Basically, I work with posets that are not ranked and I want to plot their Hasse Diagram. For the moment, I use Poset.plot() to display it but I can change to hasse.diagram().plot() if necessary.

My problem is the following : The posets that I work with come with an extra function that associate to every set an integer. Is there a way to use this function to specify the heights of the sets in my plot and not the default one ?

Thank you
