Hi everyone,
I have been searching for an easy way to draw the x and y axis on a plot but cannot seem to do it. For example, if I have a plot that has range [-2 10] for x and [-200 400] for y, I would like to be able to draw a line along x = 0 and y = 0. I have looked at certain functions such as axescenter but this draws the axes in the exact center so it does not work for me. The style is great but I can't get it along the axes. Anyone have any ideas?

xL = xlim;
yL = ylim;
line([0 0], yL); %x-axis
line(xL, [0 0]); %y-axis

Why does everyone give such complicated answers to this question? The answer is xline(0) and yline(0).

Thanks, Sajib, but I don't know how to move it to the top. I think an administrator has to do that. I think that in an earlier version of MATLAB, the answer at the top was the correct one, but the answer I gave must be a new feature.

Probably because these functions only appeared in R2018b. Still, useful to know they're there now.

As of release R2015b you can set the axes XAxisLocation and YAxisLocation properties to 'origin' to get the axes lines to cross at the origin.

A parametric equation to plot the function x= 1.5 sin(5t), y= 1.5 cos(3t) , plot the function for 0<=t<=2* pi. Format the plot such that the both axes will range from -2 to 2.
