[AA,LL] = spy(RANGE,X,...)
X
[ tseries ] - Input tseries object whose non-NaN observations will be plotted as markers.
RANGE
[ tseries ] - Date range on which the tseries observations will be visualised; if not specified the entire available range will be used.
AA
[ tseries ] - Handle to the axes created.
LL
[ tseries ] - Handle to the marks plotted.
'dateformat='
[ char | irisget('plotdateformat') ] - Date format for the tick marks on the x-axis.
'datetick='
[ numeric | Inf
] - Vector of dates locating tick marks on the x-axis; Inf means they will be created automatically.
'names='
[ cellstr ] - Names that will be used to annotate individual columns of the input tseries object.
'test='
[ function_handle | @(x)~isnan(x) ] - Test applied to each observations; only the values returning a true will be displayed.
