Why doesn't the quiver object property MaxHeadSize work?

Changing the quiver object property MaxHeadSize has no effect on the displayed quiver object.

I still find this problem, using 2016a. I am able to change the arrow head size using the test code:
q = quiver(1:10,1:10);
%Observe the figure after doing each of these
q.MaxHeadSize = 0.1;
q.MaxHeadSize = 0.01;
q.MaxHeadSize = 0.5;
but can't get it any larger than 0.5. For my data, this makes it impossible to see which direction the arrow is pointing...
Any suggestions?

Which MATLAB release are you using? This might be helpful:

Can you share a sample code with which you can see the issue? Which operating system are you on?

Hi Kevin,
I tried the following in MATLAB R2015a and it worked:
q = quiver(1:10,1:10);
%Observe the figure after doing each of these
q.MaxHeadSize = 0.1;
q.MaxHeadSize = 0.01;
q.MaxHeadSize = 0.5;
If you find that this example works and you are facing issues with the particular figure which you have, can you please share your code (and data) so that I can reproduce the issue at my end?
Hope this helps,
Abhiram.

Here's my findings... Testcode:
function tst
close all
figure(3)
clf;
hold on
for ii = 1:15
quiver(ii/2, 0, 0, 1, 0, 'MaxHeadSize', ii/10);
end
for ii = 1:15
quiver(ii/2+0.125, 0, 0, 2, 0, 'MaxHeadSize', ii/10);
end
for ii = 1:15
quiver(ii/2+0.25, 0, 0, 3, 0, 'MaxHeadSize', ii/10);
end
figure(4)
clf;
hold on
for ii = 1:15
p = quiver(ii/2, 0, 0, 1, 0);
set(p,'MaxHeadSize', ii/10);
end
for ii = 1:15
p = quiver(ii/2+0.25, 0, 0, 2, 0);
set(p,'MaxHeadSize', ii/10);
end
figure(5)
[x,y] = meshgrid(0:0.2:2,0:0.2:2);
u = cos(x).*y;
v = sin(x).*y;
subplot(1,3,1)
quiver(x,y,u,v);
subplot(1,3,2)
quiver(x,y,u,v,'MaxHeadSize', 0.8);
subplot(1,3,3)
quiver(x,y,u,v,'MaxHeadSize', 5);
end
Prior to 2015a, the MaxHeadSize = 1 leads to wrong results if the length of the arrow is not 1, this is fixed with 2015a.
MaxHeadSize > 1.1 does not seem to have any effect (with the chosen data)
The MaxHeadSize Property does not have any effect on the example code taken from here
