How do I make the arrows dashed, and make the color for each arrow different, corresponding to its z value?

Adding the 'Linestyle',':' for dashed line option makes the arrows look rather strange.

For the colors, I tried creating an nx3 matrix lineColors where each row is a color for the corresponding element, and added the option " 'EdgeColor',lineColors ", but got an error:

"Color value must be a 3 element numeric vector"

Any help is appreciated. Thanks.

Regarding W & Jacopo,

setting the view before the arrow functions solves your problem e.g.:

clc; clear; close all

xvector=[1 0 0];
yvector=[0 1 0];
zvector=[0 0 1];

figure
grid on
daspect([1 1 1])
xlabel('x [mm]', 'FontWeight', 'bold')
ylabel('y [mm]', 'FontWeight', 'bold')
zlabel('z [mm]', 'FontWeight', 'bold')

%Here goes the view setting
view([1 1 1])

arrow([0 0 0],xvector, 'EdgeColor','k','FaceColor','k')
arrow([0 0 0],yvector, 'EdgeColor','b','FaceColor','b')
arrow([0 0 0],zvector, 'EdgeColor','r','FaceColor','r')

%Not here
%view([1 1 1])

Don't no why but seems to work!
