The ability to use a detailed blown-up figure within a main figure window is not automatically available in MATLAB. To work around this issue, execute the script demonstrated in the following example.
1. Create data and plot the primary figure.
x = -pi:0.01:pi;
y = 2*sin(12*x) + 3*cos(0.2*pi+2);
plot(x,y, 'k');
2. Find the position of the current axes and then create a small axes using that position data.
p = get(gca, 'Position');
h = axes('Parent', gcf, 'Position', [p(1)+.06 p(2)+.06 p(3)-.5 p(4)-.5]);
3. You can now plot data on the second axes and zoom in on specific points.
plot(h, x, y, 'r');
set(h, 'Xlim', [-0.2 0], 'Ylim', [-5 -4]);
4. You can also turn off the tick marks on your small axes.
set(h, 'XTick', [], 'YTick', []);
After the axes are positioned as desired, You can add a rectangle and text arrow to visually link the data on the small axes with the data on your origional axes. From the figure window drop-down menu, you may select “insert->rectangle” and “insert->arrow”.
