I have a graph in which i want to highlight a point by 'o'.I want to highlight the point to see if the chosen values are in the acceptable region. Also how to shade differently the acceptable region and otherwise region on the graph.

Lets say you have a curve, and you know one point which you want to highlight. Then simply plot that point with different marker.

Ex.

a = fspecial('gaussian', [100 1],0.9); % Gaussian distriubution. 
plot(a); % you will see Gaussian curve. Now I want to highlight the maximum value.
[y x] = max(a);
hold on; % hold the plot for other curves
plot(x,y,'o','MarkerSize',10);
