Hi,

I noticed a bug with plot~ (actually I noticed it since the first release of Max6, but this is now quite annoying for an application I'm working on): with a log frequency scale, the plotting for the first bins of everything (amplitude, phase, phase delay, group delay) is systematically buggy on a log scale if the 0-frequency has a zero amplitude (high pass filter, band pass filter, etc...). Below is an example of what I mean:

Of course, if the amplitude is zero, phase has no sense and I understand that filterdetail outputs zero as well. But, as the zero-frequency is not represented on a log frequency axis, it should simply be ignored, and the plot should start with the second bin. I guess that those graphical problems are coming from that, and just ignoring them should solve the issue. Am I wrong?

Until the bug is being solved, is there a workaround to overcome it?

Best
