strange behaviour with sankey diagram (maybe a bug)

  Hi all! I'm experiencing a strange behaviour with sankey diagram. As
you can see from the attached image, the patch label it's not
positioned in the middle of the patch (as it should), but it's plotted
over the first label... The code is attached also.
Any hints?

Thanks,
  Giovanni
