Not sure I fully understand what you want. It sounds like you want 3 separate plots in a single figure? If so, look at tiledlayout.
x = linspace(0,30);
t = tiledlayout(3,1);
% Tile 1
nexttile
hold on
plot(x,sin(x))
plot(x,sin(x/4))
hold off
% Tile 2
nexttile
plot(x,sin(x/2))
% Tile 3
nexttile
hold on
plot(x,sin(x/3))
plot(x,cos(x))
hold off
