Hello, I believe the functionality you desire can be configured by using the drill down feature.
First configure your top level report definition. Include one summary column. Configure a chart on the chart tab. By default, when a chart is displayed the supporting summary data for the chart is in a table below.
If you want to display different supporting data for each value, on the report viewer tab you will see a field to enter a "custom drilldown report". The default report will display the data you want to see. You can customize that report to also be a summary report with a chart. This allows the user to drill down into the data and then back up to the top level.
