Hellow everyone,
I have attaced a figure have many traces (vertical) at different incident angles (from 1 to 30). On vertical axis there is time. I want to plot few traces at selected angles, say 5, 15, 25. I mean just three traces at selected angles instead off all angles from 1 - 30.
The code is here:
figure,
wiggle(data);
xlabel('Incident angle');
ylabel('Time'); axis([1 30, 500, 1880]);
The wiggle is a function I am calling here. It is like wiggle(data,time,angle). How I can fix it to get desired traces?

hello
this is it :
C = randn(2000,30);
data = filter(ones(1,100),1,C);
ind = [5, 15, 25]; % your angles
figure(1),
wiggle(data(:,ind), 'I');
xlabel('Incident angle');
ylabel('Time');
set(gca,'XTick',(1:length(ind)),'XTickLabel',num2str(ind(:)))
ylim([500 1880]);

The original data are left untouched
you can have your display for only one angle value by choosing the ind values , can be only 10 if you wish
ind = [10]; % your angles
figure(1),
wiggle(data(:,ind), 'I');
xlabel('Incident angle');
ylabel('Time');
set(gca,'XTick',(1:length(ind)),'XTickLabel',num2str(ind(:)))
ylim([500 1880]);
