Dashboards
A generic line chart is the wrong way to read most sensors. Wind has direction as well as speed; rainfall accumulates; occupancy is a state, not a trend. Dashboards are chosen per measurement type rather than applied uniformly.
Charts that match the measurement
- Trends — temperature, pressure, water level and similar continuous quantities, as lines or filled areas with a live value.
- Wind — speed with direction, since a wind reading without a bearing is half a measurement.
- Availability — bike docks, EV chargers and parking bays lead with the current state, not a trend line.
- Particulates and radiation — scaled to the ranges those measurements actually occupy, so a normal day does not look like a flat line.
Five time ranges
Every dashboard offers 1H, 1D, 1W, 1M and 1Y. The windows are pre-computed per sensor rather than resampled on request, which is what makes switching between them immediate.
Honest about missing data
When a sensor has no recorded history, the dashboard says so plainly instead of drawing something. A synthesised line that looks like data but is not would be worse than an empty panel — the entire value of the platform rests on every displayed value being one an instrument actually reported.
Either it was measured, or it is not shown.
