Overview¶

The analytics nodes are helpful to design flows which have array or time series data. The maximum array input size is limited to 2000.

The "analytics" nodes and their respective functions in Visual Flow Creator are described in the following sections:

Timeseries splitter node¶

The "timeseries splitter" node splits a message payload into several small messages, if the gaps between any two time series is greater than the given interval.

Extrapolate node¶

The "extrapolate" node returns the input arrays or time series data. The return value also includes the extrapolated datapoints.

Crest node¶

The "crest" node computes the crest factor for an inputted array values and time series data.

Kurtosis node¶

The "kurtosis" node computes the kurtosis for the input of array values and time series data.

Skewness node¶

The "skewness" node computes the skewness for the input of array values and time series data.

Standard deviation node¶

The "standard deviation" node computes the sample or population standard deviation for the values referenced by the defined input parameter of the array or time series.

Variance node¶

The "variance" node computes the variance for the input of array values and time series data.

Derive node¶

The "derive" node calculates the derivative for the input of array values and time series data.

Integrate node¶

The "integrate" node computes the integral for the input of array values and time series data.

Interpolate node¶

The "interpolate" node interpolates the value referenced by one parameter of the time series using linear or cubic spline interpolation.

FFT node¶

The "fft" node returns an array with the parameter values of the defined parameter, discarding other time series information.

Extract parameter node¶

The "extract paramater" node returns array values which are defined to be extracted in the parameter.

Moving average node¶

The "moving average" node calculates the moving average for the input of array values and time series data.

Map node¶

The "map" node maps time series data values to new values.

Filter node¶

The "filter" node filters the given array values and time series data based on the defined parameter.
