=============
Hi,
I'm trying to plot a Histogram given a list of (value, frequency)
pairs. It looks like the old package function Histogram will allow
this using the FrequencyData option, however, this option has been
removed from the built-in implementation in V7.

Does anyone know why this was removed, and whether there is an
alternative way to do this?

Thanks, P.
