question regarding figures in ploting graphs or surface

If I have created two or more figures, say figure 1,2,3.. in matlab, and each of them has a surface or any graph plotted in them. So If I want to create a new plot without creating a new figure, the new plot is plotted in the nth/ last figure. what do I do if I want the final plot to be in the first figure?

Use hold on and use plot(...) inside figure(1)

Be careful referring to figures by number. If someone had a figure already open before running the code that tries to plot into the "first figure" that "first figure" might not be figure number 1. Like referring to gcf or gca this is something that's probably okay to do when experimenting in the Command Window but you may want to be stricter in a function.

When you create the "first figure", store its handle in a variable that's going to be accessible to the code that creates the last plot. Use that handle (or perhaps a handle to the axes contained in it) to plot that last plot.

a = gobjects(1, 4);
for r = 1:4
    a(r) = subplot(2, 2, r);
end
[x, y, z] = peaks;
surf(a(3), x, y, z); % Make certain this surface is shown in subplot 3

Yes that’s a robust approach , thanks Steven!
