How to multiply x axis by constant?

[Richard Smith]

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:
[code]
Dim factor = 2.0
Signal(data.Y, data.X * factor)
[/code]

In this example [b]data[/b] 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.
