I have a question on thingSpeakPlot.
How do plot against time on the X axis.
Im currently using plot shown below. The problem is when there is a power failure there may be less than 250 data points in that day which then gives an error.
I would also like to include the current day which may only have a few data points.
Notice the time shift in the 3 day temperture comparison following power failure.
'xlabel','Time Measurement number','YLabel','Temperature C', ...
'Title','3-Day Temperature Comparison');
