# Health Heatmap

> A dashboard item with one row per asset and one cell per day, coloured by health, so a slow decline and a recovery after maintenance stand out.

The **Health Heatmap**  shows every asset's health day by day. A
slow decline that nobody notices from one day to the next shows as a row turning from green to red, and a maintenance
as the colour coming back. Use it beside an asset health overview, for the weeks behind today's figures.

- **Rows.** One per asset, the asset with the lowest health now at the top.
- **Cells.** One per period, in five shades: two greens above the watch threshold, two ambers between the thresholds,
  and red below the act threshold.
- **Legend.** Above the grid, naming the three states.
- **Tooltip.** Point at a cell to read the asset, the period, the health and its state.

Select a cell to filter the other items of the dashboard by that asset. With many assets the item scrolls.

## Data fields

All three fields are required: one row per asset and period, with the health as a score from 0 to 100.

## Settings

**Watch below** and **Act below** set the colours, as on the
[Asset Health Board](https://proxus.io/docs/analyze/dashboard-items/asset-health-board). Use the same values on both items.

## Where to see it

The Meridian demo plant uses it on **Meridian · Condition Monitoring Command Center**.
