Hello everyone,

I have some flux data to demonstrate and I'm going to use quiver plot. There is sometthing I have noticed that quiver scales U and V vectors according to the X and Y values. Can I prevent quiver to scale acc. to X and Y values?

Here is an example;

dir1=ones(5); dir2=ones(5)
lct1=1:5; lct2=1:5
quiver(lct1,lct2,dir1,dir2)
dir1=ones(5); dir2=ones(5)
lct1=1:5; lct2=5*lct1;
quiver(lct1,lct2,dir1,dir2)

2 outputs are somehow different and I cannot find how to tune it.

Regards,

Said

You can make "scale" 0 or "off"

quiver(lct1,lct2,dir1,dir2,'off')

Official Help on quiver: "To disable automatic scaling, specify scale as 'off' or 0. When you specify either of these values, the AutoScale property of the quiver object is set to 'off' and the length of the arrow is determined entirely by U and V."
