Most likely you have so many points that the dotted line between them is super short, like a pixel. What if you plot just a few of your points? Also green is very hard to see against a white background. Try a darker color. As you can see below, with only 10 points you can see the dotted line.

% Create sample data

numPoints = 10;

x1 = 10 * sort(rand(1, numPoints));

x2 = sort(rand(1, numPoints));

F = rand(1, numPoints);

% Plot data

plot(x1 - x2,F,'g:.', 'MarkerSize', 22);

xlabel('Displacement(m)')

ylabel('Spring Force(N)')

legend('F')
