I am playing with the API for showing the latest value of a given chart.
As a test, I'm using this channel feed:
Id' like to append the degree sign, so the link i'm using looks like this:
Now, Id' like to use the degree ° sign in the append code, but so far, I have not been successful.
I have tried the following for the append tag:
ALT+0176 (which inserts °)
%B0 (URL encoded)
° (HTML code)
%26deg (substitute & with %26)
Neither has worked. Could you please advise how to use special signs in the append tag?
Also; it would be nice if you could add the '&dynamic=' tag to the API for call ing the latest value. That way, if i include the link in an iframe, it would always show the latest value in the iframe, without me having to reload the page.
(I'm imagining something like this:
<iframe width="60" height="30" style="border: 1px solid #cccccc;" src="http://api.thingspeak.com/channels/9/field/1/last.txt?append= C&&dynamic=true"></iframe>
