For educati= onal=20 purposes I try to simulate a ammeter for reading practice.
I would like create six or more ammeter with different=20 readings, but i'm not able to do that because metapost create the same=20 random number every time I call the buffer that defines my ammeter.
=

How can I fix that?
Is there a reason why you use \externalfigure because the width can be=20 set with \scale, e.g.

=C2=A0=C2=A0=C2=A0 \scale[width=3D8cm]{\getbuffer[ammeter]}
