Drawing lines on a chart

[anthonyroche]

Does anyone know of a product that allows a user to draw a line on a
chart?
eg A historical stock tracker would have a line graph of say Aug 03 to
Dec 03, which is a line graph representing a stock over that period. I
want to give the user the functionality to draw a line on the graph
(Straight line) representing what they consider the trend. All web
based..

Any information would be of great help, I have already the component
that does the charting side, but its the line drawing that has got me
stumpped.. How does the browser detect where the user wants the line
to start and end etc

Thanks
Anthony Roche
