How do I edit the graph to get the x and y axis at 0 to line up at 0 instead of the way it is spaced?

I'm assuming you don't want to loose the points with y < 0. Something like this should work...

% test data
x = 1:100;
y = linspace(1,60) + randi([-5 5], 1, 100);
p = scatter(x, y, 'filled');
lsline;
ax = gca;
ax.YLim = [-10 70];
ax.XAxisLocation = 'origin';

In that case, look for the XAxisLocation property in the Property Inspector and set it to "origin".

Thank you, it worked!

Cheers!

Does the axis command do anything:

axis([0 70 0 70])

How would I add the axis code in the Figure window? I don't have any code that I have created. I used create plot then opened the Figures window to add the regression line.
