I'm using Mathematica 3.0 on both a Macintosh (PowerMac 8500 running
System 7.5.5; has Adobe Type Manager 4.0) and a Sun (SPARCstation 20
running Solaris). On both platforms, rotated text fails to display
properly. The letters come out in roughly the right places, but the
letters themselves stay in the normal orientation rather than being
rotated 90 degrees CCW. Very hard to read! However, on both platforms
if you _print_ the graph, the text is rendered properly. Is there, I
wondered, something that I am doing wrong that causes text display not
to work properly?
Wolfram's FAQ pages give the following unhelpful and slightly misleading

Since I have tried both TrueType and Adobe Type Manager with
Mathematica, both without success; and since other popular Macintosh
graphics applications seem to have no trouble displaying rotated text, I
asked Wolfram's technical support to elaborate on the above statement.
Are my system configurations simply wrong on both platforms, or does
Mathematica _never_ display rotated fonts correctly on Macintosh and Sun
platforms? The reply:

Well. I was naively hoping for an answer like, "You can correct this
problem by installing the freeware extension SuperFontManager...."; or
maybe, "We have solved this problem; you can download a patch from our
web site, www.wolf...."; or at the very least, "This problem will be
fixed in Mathematica 3.1. Please wait two years, then send us $985 for
Instead what I get is (if I may paraphrase) "We designed Mathematica so
that rotated fonts won't work on your platforms. They don't work
exactly as they were designed not to work, so we are off the hook!"
Out of curiosity, I tried rendering one of my graphs with MathReader on
a Windows NT workstation. The rotated text came out correct! Score one
more for Microsoft. (A loud Bronx cheer is heard from Macophiles in the
OK. The NT workstation is using TrueType fonts. The Macintosh is using
TrueType fonts. Mathematica can display rotated text on the NT
workstation, but not on the Macintosh. Wolfram Tech Support doesn't
know how to fix this problem, but maybe you do. If so, please respond.
