Filter to Identify Duplicate Points #285
Description
The technicians have requested functionality to automatically select points that are duplicate (same value and same timestamp) and overlapping (same timestamp but different values).
The first case can occur when a user has added points using the Add Point function, but some of those points already existed in the series. It is impossible to visually identify this since the points overlap. When the user tries to save the data series, it results in an error. They can then track down the overlapping point noted in the error message, but there may be more than one of these points, so they then have to go through the process multiple times.
The second case may occur for various reasons. This is not prevented by the business rules of the database, so it is desirable to have a method for identifying overlapping points in case this is not intentional or doesn't make sense for the data series.
I think that this should be added as an option on the Filter Points form. We can discuss more if needed.
