use a summary field for one of the axes or you'll end up displaying the same values in every
record. Caution is also advised when charting fields with related data—see

Choosing an Appropriate Layout Part
Earlier in this chapter you learned how one field can display a variety of different values de-
pending on the layout part it's in. Charts exhibit very similar behavior. Identically configured
charts can display very different values, whether placed in the Body, Subsummary, or Grand
Summary parts of the same layout (check out
Figure 15-23
). Still, selecting the appropriate
layout part needn't be a headache.
If you wish to graph information from a single record, or non-aggregate data from a found
set of records, Body is the layout part of choice. If your aim is to visualize summarized in-
formation for groups of similar records, you'll want to set up a Subsummary part on your
layout and give your chart a home there. Finally, should you want to show summarized data
for the entire found set of records, you'll want to use a Grand Summary part.
