92 FileMaker Pro User’s Guide
To include summary data on a layout (for example, subtotals, grand totals, averages, counts, and so on), you
place summary fields in summary layout parts (see
“Creating summary fields” on page 63). Summary parts
include grand summary and subsummary parts.
1 A grand summary part usually contains one or more summary fields that display summary information
(like totals) about all records being browsed.
1 A subsummary part usually contains one or more summary fields that display “subsummary”
information (like subtotals) for a subset of records. The records are grouped (sorted) by values in another
field, the break field. Whenever the value of the break field changes, the report “breaks” and
FileMaker
Pro inserts the subsummary part. Subsummary parts appear in Table View and List View
when sorted by break fields, and update dynamically whenever data in the file is changed.
For more information about working with layout parts, see Help.
Displaying data in charts
You can create bar, line, area, and pie charts to compare data graphically in FileMaker Pro.
Before you create a chart, think about the data comparison you want to emphasize, then choose the chart
type that will show the comparison clearly.
1 Bar charts are good for comparing increases to decreases, highest with lowest, how many, or how often.
You can create vertical or horizontal bar charts.
1 Line charts are most useful for showing data that changes continuously over time, such as historical
financial data.
1 Area charts are often used to compare summary data, such as sales totals or averages over time.
1 Pie charts are good for showing market share and proportion of difference, but are rarely used for
statistical analysis when comparisons must be precise.
Creating a chart
1. Open the layout in which you want to add the chart.
2. In Layout mode, click the Chart tool in the layout bar.
