How to label Y_ticks for a multi line plot using a for loop

I am making a multiline plot however I want the y-tick labels to represent each iteration (i) in the loop, instead of just giving me 4 ticks. I need this to help me identify which signal number to remove in my preprocessing. Below is a sample data to recreate the plot.

channel_n = size(all_trials);

all_trials = ones([15,15]);

x_axis = linspace(-0.1, 0.3, length(all_trials));

for i = 1:channel_n(1)

figure(1)

plot(x_axis, abs(all_trials(:,i)) + 0.2*(i-1), 'b', 'linewidth',1.2), axis auto

title(name + "Waterfall Plot"')

hold on

end

hold off

all_trials = randn(15, 15)*.1;
channel_n = size(all_trials, 2);
%all_trials = ones([15,15]);
x_axis = linspace(-0.1, 0.3, size(all_trials, 1));
figure(1); hold on
for i = 1:channel_n
    plot(x_axis, abs(all_trials(:,i)) + 0.2*(i-1), 'b', 'linewidth',1.2), axis auto
end
title("Waterfall Plot"');
hold off
yticks((0:channel_n-1)*0.2)
yticklabels(string((0:channel_n-1)))
