Zero state

Analysis pages produce nothing until you choose what to look at. Instead of leaving you in front of a blank page, Cube opens these pages with the zero state: a panel in the middle that tells you what the page does and offers two ways to start right away, over a faded preview of what the page will look like once loaded.

You find it on Trend, Events, Wind Analysis, Limitation detail, Alarms, Logs, Energy Production, Equivalent Hours, and Performance Ratio.

What the panel contains

At the top — the page name, one line describing what it is for, and two icons: the guided tour ( ), which walks you through the page controls, and the documentation ( ), which opens this guide at the right chapter.

On the left — Recents. The last five analyses you ran on this page. Each row states what you looked at (plants, variables, period) and when. One click runs it again exactly as it was: the selection, the period, and the filters come back, and the search starts on its own.

On the right — Ready-made analyses. Up to five proposals built on your own plants: the most common combinations for that page — for example all plants over the current year on Energy Production, or errors only, last 24 hours on Logs. They let you start without composing anything by hand.

The background is the real page, drawn faded with sample data: it shows the shape the result will take — which columns, which charts, which layout. It is not interactive and contains no real data.

How recents behave

Recents are per page and per user: the ones from Trend do not show up in Events, and they stay tied to your account on this browser.

Running an analysis that is already in the list does not duplicate it: it moves back to the top, and the list stays five rows long. Two analyses count as the same one when they look at the same things in the same way — the order in which you selected the plants makes no difference, and rolling windows ("last 24 hours", "last 7 days") are snapped to the current hour, so two clicks close together do not produce two rows.

An analysis enters the recents only when the request actually ran. If the page stops you first — because a plant selection is missing, or the period is not valid — it does not clutter the list.

The ✕ on each row removes that recent. Ready-made analyses, on the other hand, always stay available, even once you have used them.

Getting back to the zero state

After a search the panel gives way to the results. To go back, use Clear results in the toolbar: it empties the page and restores the zero state, with the recents updated.
