Here is how I do it, there may be others.
This is just an example.  Note the use of sprintf() and eval()

  #
  #  Now set up the plot
  #
  fbstring = sprintf("set nolabel");
  eval(fbstring);
  fblabelx = min(X) + 0.1 * (max(X) - min(X));
  fblabely = min(Y) + 0.8 * (max(Y) - min(Y));
  fbstring = sprintf("set label \"% .3f\" at %e, %e",flatband,fblabelx,fblabely);
  eval(fbstring);


Hope this helps.
