I'm not a Mac user. A right-mouse click is often called a "secondary"
click, which is possibly a "two finger" click on your Mac.

With the "pan/zoom" tool, you zoom the axes by moving the pointer
while holding the secondary button. I don't know how easy that will be
with your touchpad. I usually use the "zoom rect" tool; you drag a
rectangular outline over the area you want to zoom. You could also use
ion() to switch to interactive mode. Then use axis([xmin, xmax, ymin,
ymax]) to programmatically zoom the graph.
