Acoustic wave form plot, amplitude range -1 to 0 to +1 (left side), in dB, -0dB to inf to +0dB (right side). The right and left side would correspond to each other. Zero on the amplitude side equals infinity on the dB side. The plot displays fine except that I'm not able to get the right side to range from -0dB to inf to +0dB. Any ideas would greatly appreciated. Thank you.

hello
something like that ?
% dual plot (linear scale left , dB scale right)
yleft_ticks = (-1:0.1:1);
yleft_ticks_labels = num2str(yleft_ticks',3);
yright_ticks = 20*log10(abs(yleft_ticks));
yright_ticks_labels = num2str(yright_ticks',2);
% create plot with yyaxis
x = linspace(0,10);
y = 0.5*sin(x)+0.1*randn(size(x));
yyaxis left
plot(x,y)
ylim([-1 1]);
ylabel('Mag (linear)')
set(gca, 'YTick', yleft_ticks,'YTickLabel', yleft_ticks_labels );
yyaxis right
plot(0,0)
ylim([-1 1]);
ylabel('Mag (dB)')
set(gca, 'YTick', yleft_ticks,'YTickLabel', yright_ticks_labels );
