Image_graph plotted points value retreival HELP!

RR_QQ

:mad: :mad: Hi there I am wondering, is there any way to retreive values created and plotted in say a trend line graph (values that were returned to create the image from data set I specified myself)?

In other words lets say i have a data set from which i create a connected line graph and from which a straight or curved trend line is formed - how would i be able to get any of the plot point in this generated straight/curved line?

Thanks!!!

Best way would b using the Gd functions look up image functions in the php manual

Nugen

If you are laying out graphs by hand you will have to write all of the x,y math behind the actual image when using GDlib. We have regular bar charts that use this at our site: http://www.nugensoftware.com/stats.php

Just to get you started, the graph starts at 0,0 in the upper lefthand corner of the image that is being created when using GDlib.

Here is a Flash/PHP/XML Chart app thats easy to setup for your site:

Anyway, hope that helps.
