ploting variables from a data structure

hi,

i am having four 1x1 structures each contains 50 fields. what i need to do is subplot the 1st field from each structure, save the plot and do the same with the 2nd field from each structure and so on...

I am guessing i need to use a loop on each subplot, to plot each field, but how?

% some random structure for demo 
S(1).v = rand(10,2) ; S(1).name = 'one' ;
S(2).v = rand(10,2) ; S(3).name = 'two' ;
S(3).v = rand(10,2) ; S(3).name = 'three' ;
N = length(S) ;  % length of the structure array 
% plot 
for i = 1:N
    subplot(N,1,i)
    plot(S(i).v(:,1),S(i).v(:,2))
    title(S(i).name) ;
end

can we do the same if the field names are dynamic, actually the field names are strings which will be needed to save the plots

Very much can be done......why not..check I hve edited the code.

see https://www.mathworks.com/help/matlab/ref/structfun.html

p = structfun(@plot,S); %an example 
p(1).Marker = 'o'; % number 1 represent field 1 marker likewise you can reate a loop for markers alone to differentiate
p(2).Marker = '+';
p(3).Marker = 's';
hold off

i need to plot from different structures, into one plot, using subplot,

suppose i have four 1x1 structure lets say D1,D2,D3,D4. now each structure is having 50 fields suppose F1,F2,F3,F4,F5,F6,F8.....

so the plot will look like

SUBPLOT(D1.FA) SUBPLOT(D2,F1) SUBPLOT(D3,F1) SUBPLOT(D4,F1)

save it

SUBPLOT(D1,F2) SUBPLOT(D2,F2) SUBPLOT(D3,F2) SUBPLOT(D4,F2)

save it

*i havent writen the syntax of subplot but just trying to show you how the plot needs to look like

and these are spatial plots,

i just need to understand how to use a loop for the above
