Thank you for the responses Raffy and Sjoerd.
Sjoerd - Actually a histogram is what I am looking for. I have had no
problems generating the various other plots, but, a histogram of the
daily trading volume usually next to a plot of the daily closing
prices is a fairly standard financial chart. You are right that the
online documentation is excellent and I have been putting it to good
use. It does seem that there are a few gaps - but the FinanacialData
function seems to be fairly new so they haven't run through many of
the possible use scenarios yet.
Raffy - What you suggested has gotten me one step closer, but it is
not exactly what I am trying to achieve. What you suggested produced a
chart with a range of volumes on the X-Axis and the number of days in
which those volumes occurred on the y-axis. What I would like is the
volume level on the y-axis and days (time) to run along the x-axis.
Thanks for your assistance,
Jon
