Hi David,
From my understanding, when you read data using thingSpeakRead, timestamps get returned along with data while you only require the data and you can't seem to get rid of the timestamps. This happens when the OutputFormat value in the thingSpeakRead function is set to 'timetable'.
There are two ways to fix this-
1. You can use the 'matrix' output format if you don't require column labels and your data is made up of only numeric values-
data = thingSpeakRead(channelID,OutputFormat='matrix');
2. If your data contains a mix of numeric and non-numeric data or you require column labels then you can use the 'table' output format-
data = thingSpeakRead(channelID,OutputFormat='table');
and then remove the first column,
data=data(:,2:end);
For more details, you can refer to the thingSpeakRead documentation https://in.mathworks.com/help/thingspeak/thingspeakread.html
