Hi, I currently have an array that is finding temperature differences between two sets of quality controlled data. I have no problem finding these temperature differences and plotting them, but I'd like to know if there is a way for me to mark where there is at least a one degree difference? so:
%temp is time series object with temperature differences
for i=1:length(temp)
if temp(i)>1 temp(i)<-1
((mark this on the plot))

It appears to be plotting the timeseries and then plotting the '*' further down the axis, instead of on top of the time series. Is there any way I can "get" the elements of the timeseries itself? In other words, instead of using temp, could I use my time series object for temp, ts5, in this for loop? It tells me I cannot just use ts5(i), as it is an undefined function for time series.
