Compare against a baseline
A baseline is a saved copy of the plan a Gantt shows. Capture one, then compare the live plan against it.
Capture a baseline
Section titled “Capture a baseline”Open Tools and choose Capture baseline. The same action sits at the foot of Tools → Baseline. The Gantt starts comparing against the new baseline at once.
Compare against one
Section titled “Compare against one”Open Tools → Baseline and click a baseline in the list. Each bar then shows how its finish compares:
| Bar color | Meaning |
|---|---|
| Red | finishes later than in the baseline |
| Green | finishes earlier than in the baseline |
| Gray | same finish as in the baseline |
| Blue | the baseline does not hold this item |
A thin gray ghost under a bar shows the item’s dates in the baseline. Point at the ghost to read both date ranges.
To stop comparing, choose Clear selection. To rename or delete a baseline, use the menu at the end of its row.
A view too large to capture
Section titled “A view too large to capture”A baseline holds up to 5,000 items. On a larger view, Capture baseline is disabled until you filter the view to fewer items.
