How to show x and y axes in a MATLAB graph?
Solution 1
This should work in Matlab:
set(gca, 'XAxisLocation', 'origin')
Options are: bottom, top, origin.
For Y.axis:
YAxisLocation; left, right, origin
Solution 2
By default, plot does show axes, unless you've modified some settings. Try the following
hold on; % make sure no new plot window is created on every plot command
axes(); % produce plot window with axes
plot(% whatever your plot command is);
plot([0 10], [0 0], 'k-'); % plot the horizontal line
Solution 3
The poor man's solution is to simply graph the lines x=0 and y=0. You can adjust the thickness and color of the lines to differentiate them from the graph.
Solution 4
If you want the axes to appear more like a crosshair, instead of along the edges, try axescenter from the Matlab FEX.
EDIT: just noticed this is already pointed out in the link above by Jitse Nielsen.
Solution 5
I know this is coming a bit late, but a colleague of mine figured something out:
figure, plot ((1:10),cos(rand(1,10))-0.75,'*-')
hold on
plot ((1:10),zeros(1,10),'k+-')
text([1:10]-0.09,ones(1,10).*-0.015,[{'0' '1' '2' '3' '4' '5' '6' '7' '8' '9'}])
set(gca,'XTick',[], 'XColor',[1 1 1])
box off

I am drawing a graph using the plot() function, but by default it doesn't show the axes.
How do we enable showing the axes at x=0 and y=0 on the graph?
Actually my graph is something like:
And I want a horizontal line corresponding to y=0. How do I get that?
