Parameters overview

Measurement Point parameters control how data is named, converted, filtered, and displayed in charts and exports. Parameters can be applied globally or to specific channels, units, sensors, data types, and time periods.

Where to edit​

  • Charts → Tab Menu → Parameters Settings
  • Parameters are organized by channel; you can Test changes immediately and Save if you have permissions
User Permissions

Everyone can test parameters locally. Only Global Admins and Organization Admins can save them to the Measurement Point.

JSON structure​

Each parameter record includes a name and value, and may include filters limiting scope:

  • name (required): parameter identifier (e.g., multiplier, unit, toFixed)
  • value (required): string value; numbers and booleans are stored as strings
  • channel (optional): channel number the parameter applies to
  • validFromEpoch (optional): Unix timestamp when this parameter becomes active
  • chartType (optional): limits to a specific chart type (e.g., accelero, inclino, raw, strain, unit, environment, voltage, coordinateLocal, coordinateJTSK)
  • unitId, sensorTypeId, eventTypeId, measId (optional): additional filters for narrowing down the parameter's scope
  • application (optional): ui scope (web, mobile app, r-ext-charts = external access to data without account)

Generic parameters (apply broadly)​

  • hideData: true/false — hide matching data from charts and export
  • name: string — custom display name for a series
  • quantity: string — physical quantity label (e.g., Displacement)
  • unit: string — unit label (e.g., mm, °C, kN)
  • toFixed: number — decimal places for values
  • toFixedTemp: number — decimal places for temperature values
  • multiplier: number — multiply value before offset
  • divider: number — divide value (after multiplier)
  • offset: number — add constant after scaling
  • filterValues: semicolon-separated values to remove (e.g., "0;999;9999")
  • removePeak: number — remove single-point spikes exceeding threshold
  • aggregateByTimeWindow: minutes — aggregate by fixed window size (e.g., 5, 60, 1440)
  • aggregateByFunction: avg | median — function used within aggregation window
  • tempSensor: disabled | device | sensor | single | <channel number>
  • timeWindow: dynamic | minutes — averaging window for temperature calculations
  • useApiCalculation: true/false — prefer server-side computed values over local scaling
warning

Parameters are matched by their filters. If multiple records with the same name apply, the most recent record (by validFromEpoch) is used.

Type-specific parameters​

Some parameters affect only certain chart types (e.g., acceleration, inclination, raw/strain). See the dedicated pages:
