DESCRIPTION

This is an improved version of the axis widget. Changes with respect to the previous version are :

• the 'pack' has been moved out the widget. One has to do his own packing

• it is now possible to work in the coordinates of the axis. The following piece of code draws a line between the points (2 , 3.1) (4 , 4).

  
              
  
                
                
  $t->create('line',$t->plx(2),$t->ply(3.1),$t->plx(4),$t->ply(4));
