axis — Control axis limits, aspect behavior, and automatic fitting with MATLAB axis semantics.

axis is the compact plotting command for changing axes limits and aspect behavior. In RunMat it operates on the active axes state, so it is naturally used after plotting calls or within a selected subplot to reproduce MATLAB axis workflows such as axis([xmin xmax ymin ymax]), axis equal, axis auto, and axis tight.

How axis works in RunMat

• Passing a four-element numeric vector sets [xmin xmax ymin ymax] directly.
• axis equal enables equal aspect behavior on the current axes.
• axis auto clears explicit limits and returns to automatic fitting.
• axis tight uses data-driven fitting behavior while leaving figure-local plot contents unchanged.
• Axis settings are subplot-local because they act on the active axes state.

Examples

Set explicit x and y limits

plot(0:0.1:10, sin(0:0.1:10));
axis([0 10 -1 1]);

Force equal axis scaling

t = linspace(0, 2*pi, 200);
plot(cos(t), sin(t));
axis equal;

Return to automatic fitting inside a subplot

subplot(1, 2, 1);
plot(1:5, [1 4 2 5 3]);
axis tight;
subplot(1, 2, 2);
plot(1:5, [5 4 3 2 1]);
axis auto;
