Hello, I seem to have stumbled upon a bug in the quiver function. Whenever I call quiver as
quiver(x, y, u,v)
if the field (u,v) happens to be equal to zero at some point, then all arrows lose their head. Not only that, but the trouble persists even in other plots where the field is not equal to zero.
As an example, the code
using GRUtils
# Create example data
x = repeat(LinRange(-1.0, 1.0, 20), inner=20)
y = repeat(LinRange(-1.0, 1.0, 20), outer=20)
u = y
v = -x
# Plot arrows
quiver(x, y, u, v, arrowsize = 0.01, headsize= 0.5)
# Expand the y-axes to see the whole arrows
seems to work perfectly. However, the code
using GRUtils
# Create example data
x = repeat(LinRange(-1.0, 1.0, 20), inner=20)
y = repeat(LinRange(-1.0, 1.0, 20), outer=20)
u = y
u = -x
u[1,1] = 0
u[1,1] = 0
# Plot arrows
quiver(x, y, u, v, arrowsize = 0.01, headsize= 0.5)
# Expand the y-axes to see the whole arrows
seems to cause the arrowheads to disappear. Not only that, any quiver plot I try to make after that also has that issue, regardless of the field being zero or not.

As a note, I'm using Julia 1.6.1 in jupyter-lab.
Thank you for your attention
