Adding a point on a quiver graph.

Hi All,

I have a graph like this, how would I go about adding a point of this grid. Is this something that is a possible thing to do?

Thanks

What is "adding a point of the grid"?

Do you mean you'd like to add another quiver arrow? Do you want to add a point marker to the plot? What grid?

Sorry I mean adding a point marker to plot. Very new to MATLAB still learning what everything is called.

I have a point that i would like to add but I don't know how.

You would just use an additional plot command to add the point(s) you want with the desired marker. For example

load('wind','x','y','u','v')
X = x(11:22,11:22,1);
Y = y(11:22,11:22,1);
U = u(11:22,11:22,1);
V = v(11:22,11:22,1);
quiver(X,Y,U,V)
axis equal

hold on
plot(X(5,5),Y(8,3),'rx')
hold off

Amazing thank you, it works
