I would have to suggest RGraph... ( http://www.rgraph.net ) :-) It's
uses canvas though, so browser support is limited at the moment though
to Firefox 3.5, Safari 4 and Chrome 2.

`I've looked at the docs and I don't see how exactly it handles "x,y"
``plotting. I need the ability to plot multiple lines (which it obviously
``does) with wildly varying "x,y" values. It seems that all of these
``libraries "cheat" and force common "x" values via the labels. I need
``something like the following (all in the same chart):
`
$line_one_data = [x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y]
$line_two_data = [x,y,x,y,x,y,x,y]
$line_three_data = [x,y,x,y,x,y,x,y,x,y,x,y,x,y]
$graph->plot($line_one_data,$line_two_data,$line_three_data)

`As I said, each "line" has its own set of "x,y", and although they're
``all obviously numbers, they don't all have "y" results at the same "x
``intervals" so I need to be able to control them independently. Surely
``there's something that can accommodate this...?
