I just installed v1.210 of the software. When I run an automated graph of frequency vs distortion, the THD numbers don’t line up with the dB scale on the graph. For example, -60dB should coincide with .1% but instead, lines up with -70dB which makes no sense. Other graph I tried, power vs thd, is fine. Also, as a request, I wish the graphs would show light grey lines instead of tick marks for values between the major axis values. It can be hard to locate what is going on without them. Sure, I can take the data to a spreadsheet but I’d rather just use the graphs. ---

Hi @Johnr6697, I think I see the issue. Can you see if changing the `Y1 Max Value` on the left side of the graph will force a re-paint of the right Y axis? If so, this will be fixed in 2.211 ---

Yes, that forced a repaint with everything in the correct position. Thank you for the reply.
