Hi everyone,

I've recently been building some crystal notch filters in the region of 11 MHz. To characterize the filters I use quite a narrow frequency span, typically 10 kHz or so. The exact centre frequency may be something like 11.055 MHz and, as far as I can tell, nanoVNA Saver exports correct Touchstone files which can be plotted quite well in other applications. However, when I look at the plots generated within nanoVNA Saver itself I see that the labels on the frequency axis are displayed to only 2 decimal places (e.g. 11.05 MHz), causing several major divisions to have the same label. I see there have been relatively recent reports of issues to do with excessive rounding on the data (not frequency) axis but I'm more inclined to think that I'm simply missing something in the plot set-up. Any comments welcome.

Thanks, and best regards,
Peter.
