Viewing Device History

The Historical Data page lets you dig into any metric on any device over time – spotting a slow drift, confirming a fix actually worked, or pulling numbers for a report.

Building a Query

  1. Choose a Device.
  2. Choose a Metric – any numeric field Axion Displays Radar tracks for that device, grouped by category.
  3. Choose a Period: 1 Hour, 24 Hours, 7 Days, 30 Days, or 90 Days.

The Minimum, Average, Maximum, and Data Points summary updates instantly for whatever’s currently selected.

Comparing Two Series

Use Compare With to overlay a second line on the same chart:

  • Device mode – the same metric, on a different device (e.g. two projectors’ temperature side by side).
  • Metric mode – a different metric, on the same device (e.g. Fan Speed against Humidity, to see if they move together).

Three Ways to View the Data

  • Line Chart – the default visual trend line.
  • Table – the raw values, timestamped, with a Status column.
  • Health Map – a compact visual timeline plus a breakdown of how much time was spent in each state over the selected period.
