This idea is a follow up on the following question I created on the FME Community; https://community.safe.com/s/question/0D7Dm000000dkmTKAQ
In short, I noticed that the StatisticsCalculator always expects Summary statistics. In case you only want to calculate Cumulative statistics, you either need to
- ignore the error/warning (redCogwheel) indicating; 'Parameter 'Statistics to Calculate: ' must have a value'
- provide a dummy attribute to calculate regular 'summary statistics'.
Something about that doesn't feel right.
It would be nice to also have the option to only create Cumulative Statistics. I guess that may be possible by embedding the regular 'Summary statistics' in a Checked ParameterGroup (and be default checked), similar to how that is currently the case for Cumulative statistics (default unchecked).
