### Hypertext

Some terminals (wxt, qt, svg, canvas, win) allow you to attach hypertext to specific points on the graph or elsewhere on the canvas. When the mouse hovers over the anchor point, a pop-up box containing the text is displayed. Terminals that do not support hypertext will display nothing. You must enable the point attribute of the label in order for the hypertext to be anchored. Examples:

         set label at 0,0 "Plot origin" hypertext point pt 1
         plot 'data' using 1:2:0 with labels hypertext point pt 7 \
              title 'mouse over point to see its order in data set'
