I think the code will be like:

% Sample array
data = randi([30,40],100,3);

% Index where column-2 == 35
idx = data(:,2) == 35;

% Plot column-1 and column-3 under the condition that column-2 == 35
plot(data(idx,1),data(idx,3),'o');

vt = x(:,2) == 1410 & x(:,3) == 35 plot(x(vt,1),x(vt,5)) hold on to caompare two values can i use this?

Yes, you can use this to compare two graphs. Please try it!
