#### Dot over a letter

Hello,

In order to write 'dot' time derivatives I need to place a dot over variable
name (like \dot{x}). Is it possible to do it with gnuplot?

That very much depends on what terminal driver you're using.  Using
one of the TeX family, including pslatex, it's blatantly obvious:
'$\dot{x}$'.  Using the 'enhanced' option of the PostScript driver
(and recently some others), you can do it, too: see "help enhanced".
On most others, it's quite likely impossible.

I use enhanced PostScript driver (gnuplot version 3.8j patchlevel 0) and for
now something like this: ~x{\307} but it doesn't look very good. The problem
is that I can't shift the overprinted text vertically: ~x{.8a}doesn't differ
from ~x{a} in the output .eps file (and I really don't know why).

thank you for help,
Jack

Did you check that .8 isn't the default displacement?  I.e. did you
check other numeric values than .8?  I just tried .8 and 1.5, and
there sure does seem to be a difference, both in the .eps file
contents and in appearance.

I surely tried diffrent values -- there is no change in the .eps file.
Eventually I'll edit .eps by hand :)

That was a bug, but it was fixed recently in the CVS version.
