Both of these are related. I don't find the lack of data processing a
problem. This approach fits in very well with the Unix philosophy of small
(-ish) targetted tools. I use gnuplot all the time and it's always the last
step in a sequence of steps which include other tools to handle the data
processing (and re-formatting if required to address point 1). I use gnuplot
primarily for journal etc publications and the power of customization and
the quality of the output are close to unrivalled.

There are plenty of data processing tools available. R is one example.
Octave, with the various contributed packages, is obviously another and it
interfaces to gnuplot as well.

This is indeed one short-coming of gnuplot.
