    If I create a function where I multiply a signal dataset by a constant this multiplies the Y axis values.

    How to I do the same but multiply only the X axis (for instance time) values?

    Thanks.

    Use the following FPScript code:

    
Dim factor = 2.0
Signal(data.Y, data.X * factor)

    In this example data is the signal name.

    Thanks for the reply.

    I tried this solution and it works perfectly, however, I am wondering what the “Dim factor = 2.0” does because also just tried “Signal(signalname.Y, signalname.X * factor” by itself that also works perfectly.

    Thanks.

    Both notations are possible. The Dim statement declares a local variables and assigns a value to it. But you’re right. In this simple example you don’t need to use this variable.
