Gnuplot is primarily a plotting tool . This is probably the sort of
data processing task you could do externally , either before calling
gnuplot of by using gnuplot's system() command.
Having said that someone just posted a patch to do something like this
to gnuplot-beta mailing list. You may like to get current cvs
gnuplot , add that patch and test it.
BTW if you want to write some code you can do gaussian smoothing by
applying a finite kernel filter. In practice this is just a few values
depending on the width of your gaussian filter, not the all your data
points.
