All, The attached Metapost file uses the statsmac package by Anthony Phan. http://www-math.univ-poitiers.fr/~phan/statsmac.html And the package: mps.tar.gz To compile the attached file I use: mpost Untitled.mp mptopdf Untitled.1 I've attached the resulting file. I am wondering why the "cm" label is set in a larger font than the ticklabels. Can anyone help? David.
