Hi
I did sleep over the challenge, but havnt found any better idea. Now there is one trick I use to highlight extrema on a surface plots, I use the expression T*((Tx^2+Ty^2)<Tlim) where Tx and Ty are the derivatives (or gradient components) of the temperature field (in 2D x,y). Then by setting the plot "RANGE" to manual and seeting a minimum value larger than 0 you get a white plot with only the extrema appearing as small points (depends on the size of Tlim). If you want just the maxima, you add the conditional test *(T>0)
Now, if you have only one extrema you can imagine to make a boundary integration variable first of the logical function to get the avraging area, then of the full formula divided by the previously calculated area, this gives you an averaged maxima, complex but its working (provided Tlim is large enough to define an area >0).
But their must be an easier way inside the GUI's ?, with matlab the "max()" will in any case work out
Good luck
