    Hello,

    I am a new FlexPro user from a non-engineering background – we purchased Flexpro for its great graphing functions – our use is in finance/economics.

    Since I am a new user, I may be missing the right place to look for this in the manuals, but I can’t find any easy ways to do 2 simple things:

    a) Apply a 3-period moving average to a selected data series.

    b) To lag a data series by a no. of periods (e.g. 12 months) while plotting it with some other series.

    These should be child’s play, but somehow I can’t find the relevant functions. It is not ideal if one has to create new series manually using FP script formulae just to apply a moving average. Are there simple functions for these 2 procedures?

    Thanks in advance for your help.

    1) At first you have to calculate the number of values of three periods.

    
    3 * Period(Signal) / (Signal.X[1] - Signal.X[0])
    

    Then you can use the Signal Smoothing Analysis Object. The object calculates a smoothing average. This analysis object uses the Smooth- or the Mean-FPScript function to calculate the moving average.

    2)FlexPro offers the index operator [] or the value index operator [[]]. These operators can extract sections from signals and signal series.
