I am plotting four points:
x = [-0.13; -0.31; -1.07; -0.85] y = [-2.58; 5.21; -0.80 ; -1.14]
plot (x,y,'o')
x-axis and y-axis minimum and maximum should be same (both axes should have same scale) Here, -3 is minimum limit and 6 is maximum limit for both x and y axes.
I use lsline function to plot the least square fit line. Though both axes have same scale, however the y axis shifts upwards. ( -3 the minimum point on y axis shifted upwards)
Y-axes has less distance between the tick points. Please see the figure.
I don't know why? Please help.

add:
axis([-3 6 -3 6],'square')
after your plot command.

I think it's just a bug. I tried it in Matlab r2013b and it worked with just one axis command, whereas in r2012b I had the same problem as you. I think it resizes the line from the x value of the first point to the most right point.

This is still happening in 2016b... how can we report this to get it fixed?
