in reply to Hover over scatter plot

You might want to look at Tk::Chart. For a simple example, you can use the canvas like in the following example. It's up to you to correlate the point plots with their values.
#!/usr/bin/perl use Tk; my $mw = MainWindow->new(); $mw->geometry("600x400+50+50"); $canvas = $mw->Canvas(width => 600, height => 400)->pack(); $canvas->Tk::bind("<Button-1>", [ \&print_xy, Ev('x'), Ev('y') ]); sub print_xy { print "@_\n"; my ($canv, $x, $y) = @_; print '(x,y) = ', $canv->canvasx($x), ', ', $canv->canvasy($y),"\n" +; } MainLoop;

I'm not really a human, but I play one on earth.

[Corion]: Whee! Germanys Grand Central Airport (for Berlin, re-scheduled for the thrid or fourth time, to open now in 2018) has just fired their technical lead
[ambrus]: Corion: Is their budget estimate four times the initial estimate yet? Was the construction late by six months already three months after they started?
[marto]: I'll believe it when I see it. That's been due for many years now :P
[marto]: oddly the last time I was there I saw a zeppelin in flight for the first time
[Corion]: ambrus: I don't know how far the budget estimate has been overrun yet
[Corion]: marto: Heh ;) No, you were likely at Tegel or Schönefeld, the new one ("BER") will be somewhat outside of Berlin ;)
[marto]: Corion Schoenfeld, but my friend has been telling me about this new airport for about 7-8 years now :P
[marto]: I doubt it even exists as a building site :P
