16192 php script using jpgraph

I need a php script doing for a project. Basically I have a MySQL table which contains prices and timestamps among other things, (I've attached an example of table and data as a sql dump file) I need a web page with a textarea in it, in which I can post a sql query of the type... select timestamp, price from price where (timestamp gt(DATE_SUB(NOW(), INTERVAL 1 DAY)) AND (timestamp lt NOW())) and the page returns an XY line graph or the prices over time. with the X scaled to time, rather than using the dates as labels etc. ive attached a pic of a chart similar to what I need. I would suggest that the script be done using php and jpgraph ([login to view URL]) but java/jsp and jFreegraph or a suitable alternative is acceptable.
