I have a data file that stores about 500 numbers in a record - meant to plot a basic line graph (left to right). The numbers can be imported into a record with 500 fields or just stored in a text field - which ever is better.

The user might want to pick a few random records and plot them together - so the line graph may compare the few records together.

It seems that the google charts work from a url - so 500 points would be way to long for any url - so I guess that option is out.

Q: what is the best way to create / display line graphs in with PHP?

Thanks in advance for your help - dave
