Hi, Fannon

What about taking the graphics object from a plot
with PlotRange->All and then extracting the min, max
and max-min by using


MiMaFromPlot[gr_]:=
Module[{p3d,plrMa,plrMi}
      ,p3d=If[Head[gr]===List
             ,gr[[1]]
             ,gr
             ];
       {plrMi,plrMa}=Last[FullOptions[p3d,PlotRange]];
       {plrMi,plrMa}={(41*plrMi+plrMa)/42,(plrMi+41*plrMa)/42};
       {plrMi,plrMa,plrMa-plrMi}//Chop
      ];                    (* MiMaFromPlot *)



Regards

Adalbert

I would be grateful if anyone knows if there is any command that I can
use to extract the highest peak value from a graph in a Plot command?

Thanks alot!

Cheers......
