Creating jqplot graph in php page

Question

Im trying to learn php by doing a little project using apache server. I have a php page where I want to display a bar chart with jqplot using data i pull from a MySql query. I already have a query working giving me the data i want. The problem is i dont know how to implement this into a jqplot graph. Im guessing i need to make an ajax call but if i can avoid that i would like to. my php page code so far is here http://snipt.org/oknnl2. the javascript for the bar chart is here http://snipt.org/oknoi3.
i want the chart to render in div id=chartdiv thats on line 177. I have to visualize like 6 charts. if i can get some help on doing this one, im sure i can use the same process to build the others.
