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.
