# Revision history [back]

Look at the output below. You can see that it is possible to change the arrow style but not the linewidths.

sage: p = plot_vector_field((x, y), (x, -2, 2), (y, -2, 2), headlength=10, headwidth=10)
sage: p._objects
[PlotField defined by a 20 x 20 vector grid]
sage: P = p._objects[0]
sage: P._allowed_options()
{'color': 'The color of the arrows',

I must agree that the documentation of vector field is pretty poor. And the function definitely needs to add the functionality for linewidth, and possible other things. The plot_vector_field calls matplotlib's quiver function which has support for linewidth.
