Hi Taco,
I knew I wouldn't be able to explain what was h= appening.
The code works perfectly and the figure is clearly visible in = the component chapter-14 :

H Fabrice,

You did not provide a good minimum test because the graph by itself renders= fine:



Best wishes,
Taco
(if all else fails, you can replace \startMPcode with \startMPpage and gene= rate a standalone graph that way)
