Hi gerein,

Is there any way to make the whole line selectable and not
just the bottom point???

No. You can make the bottom point easier to select by giving it a nice big
marker.


Actually, I guess what I needed were the y values at an instance of time
on the x scale. The way it is set up now I can see the x value.

Ho do I get the y-intercept by using the y error bar???

To get the y-intercept remember your high school trig y = m.x + b

Its actually a little tricky because you need to find the two points either
side of the vertical line first. I have placed a sample called 'Intercept
Vertical Lines' on my site at
