Specifying the categories

Specify the column or expression whose values determine the
categories. In the Graph Data page in the Graph dialog box and on
the Data page in the Properties view, you can select a column name
from a drop-down list.

There is an entry along the Category axis for each different
value of the column or expression you specify.

Using display values of data

If you are graphing columns that use code tables, when data
is stored with a data value but displayed to users with more
meaningful display values, by default the graph uses the column’s
data values. To have the graph use a column’s display values, use
the LookupDisplay DataWindow expression function when specifying
Category or Series. LookupDisplay returns a string that matches
the display value for a column:

For more about code tables, see Defining a code table. For more about
LookupDisplay, see the section called “LookUpDisplay” in DataWindow Reference.
