Scheduled timeseries timestamp

Once a calculation created in Charts is saved and scheduled (thereby converting it into a time series), the associated metadata becomes fixed. This includes attributes such as units, name, and refresh interval (e.g., 1 minute, 1 hour, 1 day, 1 month).For example: Some calculations were saved and scheduled with a 1-minute refresh frequency. However, no data appears after scheduling because the underlying PI tag does not produce data at a 1-minute interval. To correct this, the refresh frequency would need to be changed to 1 hour or 1 month—but this is currently not possible. The only workaround is to delete the generated time series, redo the calculation, and save and schedule it again.
