The Y axis is useless in signal plots, as:
i) there is only axis for all signals, and
ii) the numeric labels at the ticks are not relevant to the signal(s).
Moreover, the '0' on the Y axis gets drawn over the upper tick on the Y axis of the spectrogram.
Perhaps, removing the Y axis from the signal plot, or making separate axes for individual signals would help.
