How to plot these traces after a fixed interval?

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]);

Hi, thanks,

It seems you have limitized the data as well. I want to keep data 1 -30 angles but want to plot wiggle say just at 10 degree.

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]);
