[Gnuplot-info] set xtics rotate by -45 works on one 4.2.6 but not on another

[Peter L. <pet...@gm...>]

Hi,

I have two machines. One Ubuntu 10.04 with gnuplot installed via apt-get 
(4.2.6 version). One Ubuntu 8.04 with 4.2.6 compiled from source 
(standard on ubuntu 8.04 is 4.2.2 but I want to have same version on 
both to avoid problems).

I'm using:

set xtics rotate by -45

On my Ubuntu 10.04 it works fine, but on the 8.04 the rotation is done 
90 degrees instead of -45 and the text ends up behind the graph.

Attached I have:

ubuntu804.plot, ubuntu804.data, ubuntu804.png (output), 
ubuntu804.configure.out, ubuntu804.make_install.out : these files should 
be clear that they are from the 8.04 machine. The configure and make 
output is included for how I compiled gnuplot 4.2.6 on that machine.

ubuntu1004.plot, ubuntu1004.png : I use the same input as for the 8.04.

Can someone explain how the same gnuplot version can output different 
plots? Am I missing something to enable when I configure gnuplot to get 
this "set xtics rotate by -45" to work?
