"Click on axis" line

ROOT
1

Hello,

Here is an observation:
[ul]
[li] if I draw a 1D histogram in ROOT, and then click and hold the left mouse button on an axis, a black line is drawn on the pad within the other axis ranges (which I find to be very useful in terms of quickly getting some numbers from the histogram). Once the mouse button is released, the line disappears.[/li]
[li] However, if I draw a graph instead, such line is not drawn. [/li][/ul]
So, the question: is there a way to force ROOT to draw the same kind of line also for graphs?

Thank you very much,
Siarhei.

It is not a line any more, it is a transparent area now… never-mind, it works,also for graphs.
Are you using some very old version of ROOT ?
