Steve,

The structure of your data isn't entirely clear to me, but could you use
Select or Cases statement, in combination perhaps with Part? With Cases you
could use the

pattern -> rhs form to just the data you wanted for your plot.

hi:

i want to evaluate/plot historical pricing data.

the lists have this form:

{B5----Y, {1947, 1, 7}, 236.1, 236.1, 236.1, 236.1, 0, 0}
i would like to select the first day of each year, and then the first day of
each month.
thanks for the help!
Steve
