Add a chart to the same form or report. For more information, see Create a chart. Make the Record Source property for the chart the same as the Record Source property for the form or report. Click the chart, open the chart Property Sheet by pressing F4, and then click the Data tab. The Subform Field Linker dialog box appears. If you are not sure which field to use, click Suggest for recommendations.
Save the form or report, switch to Form or Report view, and then verify that the chart works as expected.

Some of these elements are displayed by default, others can be added as needed. You can change the display of the chart elements by resizing them or by changing the format. You can also remove chart elements that you do not want to display. The following diagram shows the basic chart elements. Top of Page What charts can you create?

Typically, you choose one field for the Axis Category dimension and one or more fields for a Values Y axis dimension, each of which becomes a Data Series.
If you choose more than one field for an Values Y axis dimension, consider plotting along a separate Axis.

This means that the Indexed property for these fields should be set to Yes No Duplicates. If both fields have a unique index, Access creates a one-to-one relationship. This means that the Indexed property for this field should be set to Yes No Duplicates. The field on the many side should not have a unique index.
It can have an index, but it must allow duplicates.
When one field has a unique index, and the other does not, Access creates a one-to-many relationship.
