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
