    There’s a dataset which has e.g. 20000 points of data.
    I’d like to divide this dataset to 20 datasets.

    The first divided dataset has;

    First data point of original dataset,
    Second data point of original dataset,…
    1000th data point of original dataset

    The second divided dataset has;

    1001st data point of original dataset,
    1002nd data point of original dataset,…
    2000th data point of original dataset

    …

    I know I could make every divided dataset by using index operator, but it could be complicated if I divide the original dataset into a lot of numbers of datasets.

    Please let me know if you know any way to do it with few formulas.

    1) You could use VBA to create the FPScript formulas (which use the index operator).
    2) You could use the Reshape-function to convert a signal into a signal series.
    Example:

    Formula SignalSeries

    
Dim y = Reshape(Signal.Y, {20, NumberOfRows(Signal.Y)/ 20})
Dim x = Reshape(Signal.X, {20, NumberOfRows(Signal.X)/ 20})
Signal(y,x)

    Now you can create a formula for each signal:

    
SignalSeries[0]
...
