The Summary tab on the DMS Charts dialog summarizes your selections for the retrievals. It provides a visual indication of the number of retrievals you have selected to generate charts, but not necessarily an indication of the number of charts.
If you have set options for OEE retrievals for a configuration, the caption for the DMS Charts dialog is OEE/DMS Charts dialog.
The Summary tab can be useful when you are grouping data using multiple filters, part numbers, or date ranges.
A chart that features multiple retrievals in one chart window will list as one chart, regardless of the number of retrievals it may contain.
