I'm doing some wavelet analysis on a signal, but I really dont want the COI line on the plot. Any advice on how to get rid of it?

Hi Evan, the CWT outputs everything you need to do the plot with the cone of influence.
For example:
load kobe;
% The sampling frequency is 1 Hz
[wt,f] = cwt(kobe,1);
t = 0:numel(kobe)-1;
hp = pcolor(t,f,abs(wt));
hp.EdgeColor = 'none';
xlabel('Seconds');
set(gca,'yscale','log');
ylabel('Hz');
Hope that helps
