Sorry I didn't ask the question clearly. I have a large table stored in a db. PHP plots the data in the table. I'd like the user to be able to get the relevant info of the spot when his cursor points at that spot on the plot.

This may be one of those "you can't get there from here" problems, and you'll have to rethink the presentation of your data. What's the application? I would have suggested an image and Javascript picking up mouse X and Y, but thousands of points sounds like a lot of data to throw out to the client, and a big array for Javascript to do lookups against. Thoughts: a) Try compressing the data before it's sent. Describe several adjacent, similar points with a single polygon instead. b) Zoom in, and pan across the plot. That way there's less data on each page. c) Flash? Java? They should have better response times than Javascript. A regular desktop app would be best, of course. e) Embed the label into the plot in some way. Charts on paper don't need hovering labels, maybe you don't either. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
