'Clipping' the quiver plot

I have a quiver plot in which some of the arrows are on the edge of the plot and pointing outwards. The portion of quiver arrows that are outside of the plot limit are invisible. I want to make that visible.

My research shows that there is a 'Clipping' option for quiver, it seems that by turning the 'Clipping' off, I will get what I want. However 'Clipping' off does not make any difference? What do I miss? Thanks.

In R2014b, turning the clipping off works as I would expect:

quiver(0.5,0.5,1,1)
axis([0 1 0 1])
ax = gca;
ax.Clipping = 'off';

The problem was I'm using 2013, and after switching to 2014, it works. Thanks.

A lot of the legacy clipping issues were fixed in 14b.

When anything uses "axis image", then it is not possible to disable clipping anmore... Is this desired behaviour?

figure;
imagesc(rand(100,100));hold on;
quiver(rand(100,100),rand(100,100)*20,'Autoscale','off');hold off;
axis off;
axis image;
set(gca,'Clipping','on')

This doesn't work. It only works like this:

figure;
imagesc(rand(100,100));hold on;
quiver(rand(100,100),rand(100,100)*20,'Autoscale','off');hold off;
axis off;
%axis image;
set(gca,'Clipping','on')

This issue is still bothering me, and I can't believe that it is expected behaviour... Any input on this? Or ideas for a workaround?

[William Thielicke]

No one annoyed by this issue except me?

Do you get the same clipping-disabling if you manually set the y-dir to reverse,

set(gca,'ydir','reverse')

as you get with axis image?

[William Thielicke]

No... With ydir reverse, the clipping works correctly. But aspect ratio is wrong, so this wouldn't work as a workaround.

[William Thielicke]

Adding axis equal seems to be a workaround... So it is a bug?

[Bjorn Gustavsson]

Definitely a "feature". Make a bug-report, or enhancement request, whatever it's called.

Now in R2025b Update 1, vectors are clipped when they extend vertically over the image border. But when they horizontally extend over the image border, they are not clipped anymore. This makes it IMPOSSIBLE to render a movie (as the image size varies with each image).... Still driving me crazy...

f1=figure;
a1=axes;
set (a1, 'Clipping','on')
for i=1:numel(centroids)-1
    rawimage=imread(['bubble_' sprintf('%3.3d',i) '.tif']);
    imagesc(rawimage);colormap gray
    set (a1, 'Clipping','on')
    set (gca, 'Clipping','on')
    hold on
    quiver(a1,x{i},y{i},dx{i}*10,dy{i}*10,0,'r','LineWidth',2)
    set (a1, 'Clipping','on')
    set (gca, 'Clipping','on')
    axis off;
    axis equal
    hold off
    set (a1, 'Clipping','on')
    set (gca, 'Clipping','on')
    exportgraphics(f1,['tracked_' sprintf('%3.3d',i) '.jpg'])
end
