[Matplotlib-users] Arrow class, take 2

[Dominique O. <Dom...@po...>]

Aha. I just managed to have the stem drawn. My silly mistake; i thought 
that to instantiate a Line2D i needed to pass it (x0, y0) and (x1, y1), 
but it rather expects (x0, x1) and (y0, y1). The arrow looks cool now.

My remaining problem is the coordinates. It seems that matplotlib is 
positioning the arrow using pixels as coordinates, from the bottom left 
corner of the figure window.

Is my problem a 'transformation' issue?

Thanks,
Dominique
