Hello,
> I can sucessfully create a graph using CGI Perl and GD.pm 
> and have it show up in a web page.
> However what I would like to do is to display floating text over the gif
> image when I move a mouse over it, 
> showing me the x and y coordinates depending 
> where the mouse is moved to. 
> Something similar to graphs in Ms Excel.
> Actually if I have "time values" along x axis and "velocity values" on y
> axis, I would like to display floating text near the mouse pointer showing
> something similar to "time 10:00:00, velocity 20".
> If anyone has any examples please post them too.
> Thanks
