How to represent Frequency in Hertz rather than Frequency bin.

[jamison.suade]

Setting the offset, does not result to a spectrum with a negative and positive frequency.

 I want a spetrum that is centeret at 0 and showing both positive and negative frequencies.

I dont know what to connect in my offset, to achieve it.

Then what did you get?

It just multiplied the x-axis to a larger number.

Here's the result

Hi gijude,

when you just multplied the x axis values you most probably changed the X-Axis.Range.Multiplier. You need to change the X-Axis.Range.Offset value!

Hi Sir GerdW,

I dont understand. Can you tell me what particular setting do i need to have in my offset. ? Please refer to my screenshot

That looks like you made a positive offset instead of a negative one.
