A Calculated Series works like any other data series in dataZoa, but rather than holding raw numbers, its contents are mathematically derived from other series.
In the workbench, use the Formula
Contents
Formula
The formula property is simply the math expression that defines the series.
Parents
All Ancestors
Ancestors' Order of Evaluation
Children
All Descendants
Descendants' Order of Evaluation
Circular References
A circular reference is a formula that uses any of its descendants as an ancestor, which is an error.
When a circular reference is discovered as the formula is being created, it is flagged and rejected immediately. More subtly, a formula can become circular after it is created. When this happens, the result series from the formula is invalidated and marked with an error message in the series title.
Broken References
A broken reference is a formula where one or more ancestors becomes unavailable. This can happen when the ancestor is deleted, invalid, or relies on shared data whose access has been revoked.
When a broken reference is encountered, the result series from the formula is invalidated and marked with an error message in the series title.
In the case where the break is due to a shared series with a revoked permission , the result series has a special title, Removed by Owner (RBO) so that the problem can be corrected by examining the ancestors and restoring permissions.
