DesdeChaves mailto:desdechaves@gmail.com 25. Mai 2016 um 19:09 For educational purposes I try to simulate a ammeter for reading practice. I would like create six or more ammeter with different readings, but i'm not able to do that because metapost create the same 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 set with \scale, e.g.
\scale[width=8cm]{\getbuffer[ammeter]} Wolfgang
