5 of 5 records plotted · 0 excluded for missing or invalid coordinates.

Up to 100 recorded versions, spaced by observation order rather than elapsed time. Array fields use the minimum numeric item in each version. Missing values are omitted. Select a point to open its archived snapshot; comparison actions use the current listing. History begins at the first recorded baseline.
