How to use axis(axis_handle...)?

[AX H1 H2] = plotyy(x1, y1, x1, y2)

What I want to do next is... axis([H1, H2], 13 21 -Inf Inf) but it tells me that I have the incorrect number of arguments. axis(13 21 -Inf Inf) ^That works but does not do what I want.

Any help is appreciated. Thanks :)

Try putting your desired axis bounds inside a bracket. Axis accepts this as a single argument rather than four.

 axis(axes_handle,[xmin xmax ymin ymax])
