    Hi,

    I want create a “simple” sine wave with the settings to change the amplitude, the period, and the date when the sine wave has the value “0”.

    I’ve tried some scripts using the “SIN” function but all attempts were a complete failure.

    Any help is appreciated.

    Thanks,
    Thomas

    Hi,

    I am not 100% sure if this will do what you are after, please give it a try and let us know how you go:

    Used with a Show View tool the result should look similar to this:

    Hi Matthew,

    thanks for your efforts and I will give your approach a try.

    Ideally what I want is a tool or a set of tools to make time cycle analyses as the Foundation for the Study of Cycles is doing with their app “Cycle Analyzer”.

    Here are same links:

    I know how to do some of this analysis in Excel but if in any way possible it would be great to have more time cycle analysis tools available in Optuma.

    Perhaps you can create a new “Cycle Analysis” module like the “Hurst Tool” module.

    I understand of course this in not an issue of a few weeks but perhaps you can think about it. Perhaps you can also contact the Foundation for the Study of Cycles for assistance about how to make the “Cycle Analyzer” tools available in Optuma.

    The Foundation for the Study of Cycles is back and I think they will change the way we make time analyses. It would therefore be great when Optuma is there right from the start.

    I understand of course also that this new “Cycle Analysis” module in Optuma would take some time to develop and will not be for free.

    Thanks,
    Thomas

    Hi Thomas,

    I’ll look into this.

    Have you looked at the Fourier Wave tool? You can manually set it to a single period by changing the Coefficient Type to Defined. To change the origin, you will need to manually set the start of the data range on the bar chart.

    All the best

    Mathew

    Hi Thomas,

    The periodogram tool will give you feedback on what the cycle lengths are strong. This might help you in your research as well.
