Drawing the x-axis at y=0

Hello. At least as the default option, MATLAB draws the x-axis at the bottom-most part of the graph. However, I would like to draw it at y=0 as is a common convention. Is it possible in MATLAB? (including the scale on the axis, and replacing the default axis drawn at the bottom)

Thanks, David

if all you want is dark axes on your plot at x = 0 and y = 0 you just need the commands xline(0) and yline(0). This question is all over MATLAB Central and everybody gives a more complicated solution. Maybe i don't understand the question!

xline() and yline() are new as of R2018b; a lot of the other replies are dealing with older releases.

This is incredible @Brian Russell. Thank you so much for the very simple solution to a very simple problem. I urge everyone to upvote this response so people see it quicker!

Matlab now has support for this. You can set the property of the axes handle. No tricks of FEX required. :)

ax = gca;

ax.XAxisLocation = "origin";

ax.YAxisLocation = "origin";

Thanks! This is the correct way to do this in modern MATLAB, and this should be the accepted answer.

Further solutions:

• FEX: oaxis
• FEX: axescenter

It is always a good idea to search in the FEX.

For posterity, this has been fixed in the HG2 Update. Linked below since this thread is currently the top search result on the topic.
