CHAPTER 4 Defining DataWindow Objects
DataWindow Designer User’s Guide 105
Using the N-Up style
The N-Up style presents two or more rows of data next to each other. It is
similar to the Label style in that you can have information from several rows
in the database across the page. However, the information is not meant to be
printed on labels. The N-Up presentation style is useful if you have periodic
data; you can set it up so that each period repeats in a row.
After you select a data source, you are asked how many rows to display across
the page.
For each column in the data source, DataWindow Designer defines n columns
in the DataWindow object (
column_1 to column_n), where n is the number of
rows you specified.
Table example
For a table of daily stock prices, you can define the DataWindow object as five
across, so each row in the DataWindow object displays five days' prices
(Monday through Friday). Suppose you have a table with two columns,
day and
price, that record the closing stock price each day for three weeks.
In the following n-up DataWindow object, 5 was selected as the number of
rows to display across the page, so each line in the DataWindow object shows
five days' stock prices. A computed field was added to get the average closing
price in the week:
About computed fields in n-up DataWindow objects
You use subscripts, such as price[0], to refer to particular rows in the detail
band in n-up DataWindow objects.
