Plotting with AJAX + Javascript


A friend of mine had written an application which communicates with a small microcotroled board and saves data read from this board on a mysql database. He wants to plot these data on the web. He wrote a PHP script using the GD lib. He did a real good job, but he wants it to plot the data dynamically and an http refresh made things a little ugly. He is now trying to plot directly with AJAX + Javascript. He is trying to use Flot, which is a javascrit for plotting data.
Another usefull resource for realtime web graphics is the CavasDemos.
