Threshold Types

The following threshold types exist:

• Constant thresholds:

  Threshold type that takes four constants (min, low, high, max) as thresholds. The calculation of the constant threshold is based on the corresponding signal only.

  Constant thresholds can be used with the following chart types:

  • Plot

  • Scatter

    The threshold applies to the signal data and not to the display types (e.g., min, max, mean).

  • Histogram

  • Interval:

    For stack or series display types, the thresholds can only be set on the y axis.

  • Timeplot:

    The thresholds can only be set on the y axis.

  • MinMax table

• Function thresholds:

  Threshold type that takes four MATLAB anonymous functions (min, low, high, max) as thresholds, which define the green, yellow, and red ranges. Two signals are needed to calculate a function threshold: The values of the first signal (x axis) are used to calculate the threshold values as functions of this signal and to compare the calculated values with the values of the second signal (y axis).

If you use the Configuration Creator, you can only define constant thresholds. For more information, see Setting Thresholds.
