Currently gnuplot-3.7.3 is in fedora and this is an incremental update to 3.7.1 released at the end of 1999. So there are over 4 years of developments in the just released gnuplot 4.0. Any chance it could be included? http://www.gnuplot.info/docs/gnuplot.html#What_is_New_in_Version_4.0 thanks, Pádraig.
