Hi Winnok,

if you are writing a plugin (not a macro), you could use
   myPlot.addLabel(double x, double y, String label)
you have to scale x and y however, addLabel expects coordinates
between 0 and 1.
   x = (xdata-xmin)/(xmax-xmin);
and the same for y, where xmax, xmin is the data range of the
plot and xdata is the x-coordinate where you want the label.

To get xmin, xmax, ymin, ymax you could use
   ij.util.Tools.getMinMax(data)
with the data arrays that you submit to the plot function.
