Crossing axis and labels in matlab

问题:

I just can't find it. How to set up axis and labels in matlab so they cross at zero point, with the labels just below the axis not on left/bottom of the plot ?

If I didn't make myself clear - I just want the plot to look like like we all used to draw it when in school. Axes crossing, 4 quadrants, labels right below axis, curve ... as it goes.

Anyone knows how to set it up ?

You should check out two submissions on The MathWorks File Exchange:

• PlotAxisAtOrigin by Shanrong Zhang
• axescenter by Matt Fig

Hopefully these will work with whatever MATLAB version you have (the submission from Matt Fig is the most recently updated one).

As of Matlab release R2015b, this can be achieved with the axis property XAxisLocation and YAxisLocation being set to origin.

In other words,

x = linspace(-5,5);
y = sin(x);
plot(x,y)

ax = gca;
ax.XAxisLocation = 'origin';
ax.YAxisLocation = 'origin';

Example is taken from MATLAB official documentation:

• Display Axis Lines through Origin
• Controlling Axis Location
