The "plot" function invokes different methods of plotting depending on the input data provided. Since this is timeseries data, the syntax for plotting the timeseries to a particular axis in this example would look like the following:
>> plot(x, 'Parent', h1)
This is because the timeseries plotting function uses the syntax:
plot(ts,specs)
where "specs" refers to the Line Specifications as a 'Name', 'Value' pair. This is not entirely obvious since the "plot" documentation specifies axes as the first input. More information on this syntax may be found at the documentation link below:
