Problem with Metapost
Hi, I think I have never encountered this problem. Recently, I can no longer have a succession of figures with Metapost; only the first one appears. Thanks.

Hi,
you get an error of redundant equations. Try
numeric ymax,xmax ; ymax := 7 ; xmax := 7;
numeric xmin,ymin ; xmin :=-1 ; ymin := -1;
and it might work.
(It is a bit weird that ymax = 7 several times result in an error, but ... )
