I have velocity ,v, and discharge, q, vectors . I want to draw hysteresis plot between the two. I used plot_dir function but it can't allow me to have the plot with good view and resolution. Is there any way of plotting it?
I used this function but failed
plot_dir(v,q)
Thanks for your help.
Any function that give that shows the beginning and end of successive points with arrow is acceptable. Thanks again.

x = rand(10,1);
y = rand(10,1);
quiver(x(1:end-1),y(1:end-1),diff(x),diff(y),0);
Please accept an answer if it helps you.

X = [-3:.2:3 3:-.2:-3];
Y = [tanh(X(1:length(X)/2)-1) tanh(X(length(X)/2+1:end)+1)];
patch(X,Y,[.5 1 .5]); hold on
quiver(X(1:end-1),Y(1:end-1),diff(X),diff(Y),0);

Well, all I read were 2 words hysteresis and arrow. So I guess its a patch + a quiver whats needed.

Thanks all, You answered my questions . the arrow direction is not really distinguishable is there any way of improving it? it looks straight line rather than arrow...tnx
