I have an inclined surface and 20 different specified points(x,y,z) on it.for each station I have a set of (time, amplitude) data i.e. a wave. I need to plot each wave at each related point. so a surface with 20 waves on it.

I have no idea how to do it, subplot probably won't work because I need to plot on specified points.

please help!

Here is a mock up solution.

Code is: below. I've used part of your data, but I've made up some similar data (using a sinc function) for the other trends. I've also edited your data file and stripped the header comments.

%% plot mini plots

fname = 'str-10dep00.dat';

fid = fopen(fname);

A = fscanf(fid,'%f');

fclose(fid);

A = reshape(A, 8,length(A)/8)';

t = A(:,1);

plot(t,A(:,3),'.-');

Now I've made a grid plot, and plotted the trends in row order. You will read each from a different file of course.

%% generate some interesting data

%% Now try grid

y = 2*[0:4]; z = 2*[0:-1:-5];

[Y,Z] = meshgrid(y,z);

dum = sinc(t/10);

D = [A(:,2:end), dum.*randn(length(t),23)*0.1] % store in row order

plot(Y,Z,'bo','MarkerFaceColor',[0.4588 0.7333 0.9922]);

axis(2*[-1,5,-6,1]);

xlabel('x'); ylabel('z')

hold on

for k=1:size(D,2)

s = D(:,k);

i = mod(k-1,5)+1;

j = -floor((k-1)/5);

x = (2*i-2)+t/t(end);

y = 2*j+ s/range(s);

plot(x,y,'-','color',[0.3176 0.6157 0.6863])

end

hold off
