Hello, According to the next code, how can I change the ‘markers’ and line style using the ‘findpeaks’ function? Thank you.
[pks,locs,widths,proms] = findpeaks(pws(:,end),y,'MinPeakHeight',trd);
legend('Filtered Data','Peak','Prominence','Width','FontSize',5);

ax = gca;
sig_h = findobj(ax, 'tag', 'Signal');
peak_h = findobj(ax, 'tag', 'Peak');
As you are asking to plot Extents as well, you will also have entries with tag 'Height', 'HalfHeightWidth', 'Border' (multiple); or 'Prominence', 'HalfProminenceWidth', 'Border' (multiple)
You can then set the LineStyle and Marker properties according to your preferences.

I always plot the results myself:
[peakValues, indexesOfPeaks] = findpeaks(................)
plot(x, y, 'b-', 'LineWidth', 2); % Plot original data.
hold on;
% Extract peak locations from x and y.
xp = x(indexesOfPeaks);
yp = y(indexesOfPeaks);
plot(xp, yp, 'rv', 'LineWidth', 2, 'MarkerSize', 10); % Plot triangles atop the peaks.
Or you could skip creating xp and yp and have for the last line
plot(x(indexesOfPeaks), peakValues, 'rv', 'LineWidth', 2, 'MarkerSize', 10); % Plot triangles atop the peaks.
