Updates to variables

Hi,

I want to display a text string (basically a connection string) which is comprised of multiple lines i.e.
channel 1=10.160.158.100:47145
channel 2=10.160.158.100:46789
This string is stored in a measurement having been retrieved by an http request. I’ve tried using a variable so that I can display the string in a text panel and use html (
) to separate the various lines.
The trouble is, is that the variable is only updated on a page refresh whereas I want to display to be dynamic such that it refreshes in the normal way of a panel.

Is there any other way of displaying multi-line text that will updated dynamically? The Text panel doesn’t allow me to use a query.

TIA
Martin
