I do this with some timed javascript functions. I don't use the webserver
built into intermapper, but instead on another server and just pull the
chart images. There may be a much better way to do it and if so I'd like
to see what it is. :)
An empty img tag like so:
<img id="inetusage" style="vertical-align: top;"/>
Then when the page is loaded, execute a function with a timer like so
(refreshTime is number of seconds between image refreshes):
setTimeout("loadInetUsage()", refreshTime * 1000);
Inside that function you set the source for the img tag:
var usageImg = document.getElementById("inetusage");
usageImg.src = 'http://intermapper-net.utc.edu/g4d181a12/chart/Internet
Traffic/*chart.png?timescale=' + scale + '&width=' + width + '&' + new
Date().getMilliseconds();
And then at the end of the function, reschedule the timed function call.
The date at the end of the img source address insures that it grabs a new
image every time instead of just reloading a cached one.
