Re. errorbar plots, here's my pet peeve. I would like there to be
an octave-like system whose basic data type is 'data with errors', and
all operations calculate proper error estimates. This requires
changing the basic ops, which is not that hard, but it also requires
rewriting all the algorithms, because e.g. the error estimate of a
matrix inversion, as determined by propagating errors via individual
operations like multiply/add, is, I think, very overly pessimistic. A
realistic, smaller estimate is obtained by looking at the algorithm as
a whole.

NB, errorbar plots can always use gplot directly

    tmp=[(1:10)',sqrt(1:10)',sqrt(sqrt(1:10))'];
    gplot tmp with errorbars
