Sorry for filing this bug without adding a description -- my click finger was
faster than my brain.

Please find attached a patch (by courtesy of my colleague Akos Lukovics) that
adds a dropbox to the IO Graph dialog from which you can choose a number of
"filters" (in a Digital Signal Processing sense, not Wireshark Display Filters)
for the Y axis config. You can choose to display moving averages over
packets/bytes/bits with different window sizes. Calculating the moving average
(rather than the average per interval, which the IO Graph dialog already
provides) has the benefit that it's less susceptible to show aliasing artifacts
for traces whose packet rates approach the current Y axis scale.
