I've embedded a chart on a web page. It's a temperature logger that has been running since July or so last year. There should be 8 or 9 months worth of data. Update frequency is 10 minutes.

I'm trying to embed a chart showing the temperature for the last year (there's not enough data for that, but I expected to get a plot of the temperature since the start of logging).

This is what I do:


The result is a plot that starts on Feb 3 - just shy of 2 months worth of data. The same thing happens if I try to view the data on Thingspeak's own web page:


Data start on Feb 3.

Are my data older than Feb 3 missing?

Go into your channel private view, click on the pencil and select "average" to 1440.

The data in your channel is intact. Perhaps you are looking for this: https://thingspeak.com/channels/129101/charts/1?average=1440&days=365

The 1440 number is = 24(hours) *60 (minutes). This needed so your data in any day does not look like a blob and your graph with historical data doesn't look like a collection of blobs.
