Examples:

To set a label at (1,2) to "y=x", use:

      set label "y=x" at 1,2

To set a Sigma of size 24, from the Symbol font set, at the center of the graph, use:

      set label "S" at graph 0.5,0.5 center font "Symbol,24"

To set a label "y=x^2" with the right of the text at (2,3,4), and tag the label as number 3, use:

      set label 3 "y=x^2" at 2,3,4 right

To change the preceding label to center justification, use:

      set label 3 center

To delete label number 2, use:

      unset label 2

To delete all labels, use:

      unset label

To show all labels (in tag order), use:

      show label

To set a label on a graph with a timeseries on the x axis, use, for example:

      set timefmt "%d/%m/%y,%H:%M"
      set label "Harvest" at "25/8/93",1

To display a freshly fitted parameter on the plot with the data and the fitted function, do this after the fit, but before the plot:

      set label sprintf("a = %3.5g",par_a) at 30,15
      bfit = gprintf("b = %s*10^%S",par_b)
      set label bfit at 30,20

To display a function definition along with its fitted parameters, use:

      f(x)=a+b*x
      fit f(x) 'datafile' via a,b
      set label GPFUN_f at graph .05,.95
      set label sprintf("a = %g", a) at graph .05,.90
      set label sprintf("b = %g", b) at graph .05,.85

To set a label displaced a little bit from a small point:

      set label 'origin' at 0,0 point lt 1 pt 2 ps 3 offset 1,-1

To set a label whose color matches the z value (in this case 5.5) of some point on a 3D splot colored using pm3d:

      set label 'text' at 0,0,5.5 tc palette z
