Built-in functions

For most database connection types, built-in functions are supported.

In the "Create signal" modal, select "Built-in" function type. Choose the signal you want to create a function for on the left, and fill in all required parameters.

Following built-in functions are supported:

Function	Description	Parameters
Moving Aggregate	Moving aggregate of a signal	Aggregate - The type of moving aggregate Window Size - The number of samples to average over
Cumulative Sum	Cumulative sum of a signal	Gain - The gain of the signal
Integral	Integral of a signal using the midpoint rule	Gain - The gain of the signal
Linear Calibration	Linear calibration of a signal	Gain - The gain of the signal Offset - The offset of the signal
Clip	Backwards finite difference of a signal, i.e. v(t) - v(t-1)	Gain - The gain of the signal
Derivative	Backwards discrete derivative of a signal, i.e. (v(t) - v(t-1)) / dt	Gain - The gain of the signal
Remove outliers, stddev	Remove outliers of a signal using standard deviation	Std - The standard deviation of the signal
Remove outliers, fixed limits	Remove outliers of a signal using fixed limits	Min Max
Sample shift	Shift a signal by a number of samples	Shift - The number of samples to shift the signal by
Zeroing	Offset the signal to be 0 at the first datapoint inside zoom range
Time	Select the time axis of a signal
