Sure i can :)
I have some issues im facing rigth now.

1) the file is text format (csv possible) and really big like 150000 lines

2) it have 7 rows in a line (123 456 789 999 999 999 999)

first i tried to build a update function, what happens is i have to run every time ajax read ( i guess so)
it is really slow and fill up the browser cache pretty fast cause it reread the the copmplete file everytime and store it.

what i want is to show a live update with the last 1000 lines and shifting the graph.
I know text format seems not to be the best source
