3D Graph dB (Z) Issue

Hi,


With the latest version of X3, when I am plotting a 3D Graph for sound dB even though it has A-Weight filter it shows like dB (Z) as in the attached picture, is there a specific reason for that or is it a bug?

Hi,


we have checked this, but if te A weighting is used, it shows (dB(A)) in the 3D graph.

Would it be possible to get the setup file where you can see thos problem?

This happens if you first apply Acoustic Weighting Filter independently (I am not talking about A weighting through FFT), thanks.

Hi,


when you are calculating with the fourier transformation mathematics, there is also a weighting option which is by default set to Lin(Z). The 3D graph will then show only the weighting of the latest mathematics.


The best option is to use the weighting directiy in fourier transformation.

Thank you, it works like the way you told but please check first applying independent Acoustic Weighting Filter you will see it gives you the wrong legend for the weighting filter, thanks.
