Usages of analytics nodes - Developer Documentation

# Usages of analytics nodes¶

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

## Extrapolate¶

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

## Crest¶

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

## Kurtosis¶

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

## Skewness¶

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

## Standard deviation¶

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

## Variance¶

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

## Derive¶

For inputs of array values and time series data, derivative is calculated for a set of data points.

## Integrate¶

The nodes compute the integral for the input of array values and time series data.

## Interpolate¶

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

## FFT¶

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

## Extract parameter¶

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

## Moving average¶

For inputs of array values and time series data, moving average is calculated for a set of data points.

## Map¶

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

## Filter¶

For a given array or time series data, the node filters and passes the filtered values to the output.

## Timeseries splitter¶

For a given array or time series data, the node splits a message payload into several small messages if the gaps between any two time series is greater than the given interval
