Calculated Series

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.

Calculated series have all the normal properties of a data series, plus a few special ones.
In the workbench, use the Formula

icon next to the title of a calculated series to pop[ up these Calculated Series properties:

Formula

The formula property is simply the math expression that defines the series.

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 This can happen when the ancestor is deleted, invalid, or relies on shared data whose access has been revoked.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.
