Windows or Linux?
In windows, I suggest you update to 5.12:
http://sourceforge.net/project/showfiles.php?group_id=4933
after uninstalling previous version. This executable contains gnuplot
4.2 and you are done.
In Linux, it depends on your distribution how to update your programs.
Let me know if you have problems.
