how to keep the scale on the axis the same on a graph?

I have a code which plots the ellipses of a tidal cycle. The x and y axis are the North and West co - ordinates on a graph. When plotting I need to keep the distances between the axis labels of y and x the same or else it visually makes the result look different. Is there a matlab function to keep the x and y scaling the same?
