watch labels

By default, labels are always generated for the target "watch mouse". You can turn labels on for other watch targets using the command set style watchpoint labels. The label text is "x : y", where x and y are the coordinates of the point, formatted using the current settings for the corresponding axes.

Example:

     set y2tics format "%.2f°"
     set style watchpoint labels point pt 6
     plot FOO axes x1y2 watch mouse
