Point out a specific value in a plot.

Following is the code to minimize a Sol over Q. The minimized value is obtained at Qmin. I want to plot Qmin on the plot for Q vs Sol. At the least tell me how to determine how look for its data point in the Q array.

x1 = 5900000;
x2 = 8800000;
Qmin = fminbnd(@Sol, x1, x2);

Qmin
disp(Qmin);

 Q = 5900000:10000:8800000;
  diff = Sol(Q);
  diffQ = Sol(Qmin);
  plot (Q,diff)
  xlabel('Assumed Flux(Q)');
  ylabel('Assumed Flux(Q) - Obtained Flux(qr)');

Easy no...use plot and hold on

Sorry. I am a newb. I've tried plot hold on but, we need a specific data point number of Qmin to point it out in the plot.
