Plotting on y-axis in form of offset for clarity ?

I have data A (first column x axis, and following column are y axis, trying to plot such that y axis have some offset for clarity), I don't want to put some additional value to this, without putting additional value, How can I plot directly on y axis, so that it will have some offset on y axis. Thanks.

plot(A(:,1),A(:,2));
hold on
plot(A(:,1),A(:,3)-0.3;
plot(A(;,1), A(:,4)+0.3;

your solution should work, provided you close the parentheses

 plot(A(:,1),A(:,3)-0.3); 
 plot(A(;,1), A(:,4)+0.3);

didn't you get an error message?

yes, Is there any other methodology or something else, because sometime the guess value of 0.3 or 0.4 is too much for plot and plot changes to line form.

That is a bit too vague.

You're asking for a code that decides what is the optimal offset for producing a clear plot.

However "a clear plot" is kind of a subjective notion.

Have you considered alternatives, such as a waterfall plot? See

 doc waterfall

Update note that waterfall works along rows

What I was suggesting above is to use a third dimension to "offset" your data. You can do that also with "plot3". Whether this produces an acceptable plot depends on your data and your personal taste.

About your original question, you could perhaps do something like this

 hold on
 plot(A(:,1),A(:,2));
 os = max(A(:,2))-min(A(:,3));
 plot(A(:,1),A(:,3)+os);
 os = os+max(A(:,3))-min(A(:,4));
 plot(A(:,1),A(:,4)+os);

and so on. You can put that in a loop, if you have many columns.
