I don't know this function (don't have the associated toolbox), but for what I see in the doc, you can do it.
First, check the HandleVisibility property of your figure. it should be set to callback.
Then, ckeck that your axe do have the tag axes1.
Finally, you can plot your data in the axe you want using the syntax
check that axeshandle is not empty (put a breakpoint in your code at this line)
