I am making a very simple scatter plot.

pts = [1 1; -2 1];

scatter(pts(:, 1), pts(:, 2));

As we see, the xlim is automatically determined by MATLAB to be from -2 to 1, which is satisfactory to me.

What annoys me is that the origin 0 is not centered. That is the x-axis is asymmetric around 0. In this particular example, I want the x-axis to be from -2 to 2.

I can surely find the largest absolute value, which is 2 in this case, and manually do xlim([-2 2]). Is there a more elegant way, like axis center in my imagination?

I am making a very simple scatter plot. `pts = [1 1; -2 1]; scatter(pts(:, 1), pts(:, 2));` As we see, the `xlim` is automatically determined by MATLAB to be from `-2` to `1`, which is satisfactory to me.
