Prevent data from touching axes

In MATLAB, is it possible to quickly/concisely increase the default padding around data in plots? In other words, I don't want the data to be too close to the axes.

For a Matlab version recent enough, you can use the axis padded command after your plots.

This approach is similar to @jodag's excellent answer and is entirely my preference. Posting this based on OP's request in the comments. I have no doubt there may be more efficient ways of doing this.

Key Idea: Automate use of xlim and ylim.

Minimal working example:

d = 0.10;     % 10 percent
c = [1-d 1+d];
X = 5 + 5*rand(10,2);

plot(X(:,1),X(:,2),'rs')

Xrng = xlim;
Yrng = ylim;
xlim(c.*Xrng);  % Adjust X Range
ylim(c.*Yrng);  % Adjust Y Range

Other ways to automate this using these properties:

  1. Use a handle for the plot h = plot() and modify properties
  2. Use the set, get, and gca commands.

No doubt there are other approaches still.

If simply padding the existing axis is sufficient then the following should work. Say you want to add 10% to each side.

plot(...);
scale = 1.1;
ax = axis();
xc = 0.5 * (ax(1)+ax(2));
yc = 0.5 * (ax(3)+ax(4));
c = [xc,xc,yc,yc];
axis(scale * (ax - c) + c);
