Before I tried using this Increment code, it plotted the correct points but with a wrongly labeled x-axis (every minute instead of every 10 minutes).I have a feeling the NaN in my t array is the cause of this
You may "have a feeling" but you'd be wrong... :)
plot very nicely just ignores NaN leaving holes in the plot.
If you got one-minute increments, that's because the X-vector is undoubtedly on a range of 1:N instead of actually in minutes.
As I said in answering your previous question on the same subject, if you want a time axis w/ date/time, then the easiest is to convert to datenums and use datetick.
If, otoh, the data are at 10-minute intervals and are none missing (or the missing locations in the time vector are filled w/ NaN), and you want to plot from 0 to length of the data series on a 10 minute interval, just use
t=[0:10:10*(length(x)-1)];
which is, of course, just
t=10*[0:length(x)-1];
for the plot x-axis vector. IOW, build the 10-minute interval into the data.
Or, use 1:length(x) and reset the x-tick labels but this is more work than simply making the time vector and using it.
