Tooltip text for dynamic buttons

programming flash
1

Can anyone please answer my few queries?
Please refer the graph attached

  1. What would be the best way to draw the multi line graph in Flash?
    I first used the charting component but I guess it doesnt supports multi-line

  2. Also, I want to add dynamic buttons( the triangles etc you can see) and each button should have a different tooltip text depending on the coordinate where they are placed.

  3. Also, as the graph progresses in the horizontal direction, it should auto scroll.
    Would it be possible using the scrollbar component?

Thanks
