I have worked with Fusion charts and jpchart, but what I need is a charting library that will allow for points to be relative distance in a line graph.
For example: we have timed transactions so that the points for 10 minutes difference are closer than 30 minutes and 60 minutes.
Most examples I have found show all points equidistant from each other.
Also, I need to be able to save the graph as an image in PHP backend code.
many thank yous in advance
Todd
