Hi Kling75, I think there are some confusions here. What we were was suggesting was to change your Graph Axis Limits. The human ear is capable of detecting 1dB change in SPL, so we want to see 1dB increment in the vertical axis.
Two ways to achieve that. You can simply use the +/- bottoms to increase/decrease the vertical increment, or as Chromatischism suggested, set fixed numbers on Graph Axis Limits.
Here is an example. The attached Pic1 and Pic2 show the exact same frequency response. Pic1 uses the settings Chromatischism suggested, it shows some huge ups and downs. Pic2 uses your latest settings, the ups and downs are much more compressed, so that unevenness is much less visible.
I believe it would be beneficial for you to change your graph settings. It would simply reveal more information.
