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')

Also can you tell me how to get a graph like this in matlab which has completely white background.

You forgot to tell me how many points you were plotting. AND you forgot to attach your data so what else can I do?

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
