Just out of curiosity: why did you refer (only) to examples instead of 
the documentation?

The combination of these two may not work very well.  They're both 
global display mode changes, and they disagree on how the plot should be 
done.

You'll want to use the "using" specification.  I suspect you need 
version 4.2 for that to work with 'matrix' data.

I don't think there is any such thing --- and I guess I'd know about it 
if there were ;-)

See "help colorbox"

See "help xlabel"

The tick labels are output in the default font of the terminal.  That's 
the one you chose in the "set terminal" command.  And update to 4.2 
would offer more flexibility.

In the terminal driver you chose, you don't.  See "help enhanced" and 
"help pslatex" though.

You'll want to start by "help set terminal", and continue by "help 
pslatex".
