Remember that the underlying data units will still remain the same, so I'd remove the call to "xlim" and "axis", since you're limiting the window to not display the full range of data. Help us identify new roles for community members, Proposing a Community-Specific Closure Reason for non-English content. Other MathWorks country or more simply/more generally, just iterate over all of the handles at the end: EDIT: a more comprehensive solution to show construction of the subplots in two parts -- things that differ vs things that are consistent.
