You could use the utility I mentioned in your other post:

Also, you can set up dynamic ranges that include pivot table data, and use
them to create dynamic charts:

I update a table in excel (2003) each month, showing year to date data.
I need to pivot the data into many pivot tables then create charts (I
don't
want to use a pivot chart for cosmetic reasons).
Because it is year to date, I would like the charts to automatically
update
each time I add a new month (date is on the X axis).
At the moment I change the source data each month for each chart to
include
the new month, but I was hoping someone could tell me an easier way of
doing
this.
Thank you
