Is there any way to create a running text log with messages from my arduino to appear in another window with my temperature chart?

What is this called? I just need a lead on what to call this so I can go look at how to do it.

Thanks

I believe you can send text to a channel field. In fact, if your not careful, you will send numbers with white space to ThingSpeak, and it will treat them as text. In Arduino, use mystr.trim(); to fix the white space problem.

ThingSpeak has a status field for each channel that would seem a good fit for storing your status messages.

To display you may have to use something like a Google Viz annotation chart [1] or dygraphs annotations[2]. I've posted some code using Google Viz at https://gist.github.com/rw950431/8815072 which you may be able to adapt.
