In the "Purge now" frame of a datapoint edit page there is a "purge now" button that purges value entries older than xx age.
However, this does not allow point values to be purged conditionally based on their age or value. This is important because often we realize we need the "Discard extreme values" feature only in hindsight, after there has been a malfunction and the erroneous data is already stored in the point value database. It is also a problem because we may want the extreme values stored and plotted in order to troubleshoot them. For instance, if it weren't for plotting extreme values, I would not have realized that the import function was causing zero values to be stored in the point value database.
Can you please include additional purge conditions in the "Purge now" frame?
[list] Purge points between start time ss and end time ee[/list]
[list] Purge points between start time ss and end time ee if value > A OR value < B[/list]
[list] Purge points between start time ss and end time ee if value = 0
