Frequency reference curve visualisation

I have created a frequency reference curve as an amplitude limit to display on an FFT plot. I notice that when I scale the FFT plot's x-axis, the limit curve does not scale with the correct values. In the attached screenshots, the 'correct limit' shows the limit curve ending at 1MHz with an amplitude of 0.1. When I scale the x-axis, the limit curve moves and now displays 0.1 at 500kHz, with the interpolation in between being now also incorrect. Is this a visualisation bug?

Dear Edward,

we tried to reproduce the issue on our site but we could not reproduce it. Would it be possible that you provide a data file, so we can see closely this behaviour?

Also we would need the information on which version of Software are you using? And what kind of settings do you use when creating the frequency reference curve.

Regards

Hi,

I'm using Dewesoft X3 Version: SP7 (RELEASE-190607) (64-bit)

Attached is the frequency domain reference curve setup.

Dear Edward,

we can see now that this is clearly a bug. We will report it and will inform you when there is an update on this issue.

Dear Edward,

we would like to notify you that if you present the frequency signal and the reference curve on the 2D graph the visualisation of the results is correct.

Our developers will of course also change the visualisation of the FFT visual control, but as this is a bigger task it would take more time to fix it.

Regards
