VectorGlyph¶

VectorGlyph renders a 2-D (u, v) field over (x, y) positions as arrows (quiver), wind barbs (barbs), or streamlines (streamplot), coloured by the per-vector magnitude hypot(u, v).

1. Arrows (quiver)¶

In [2]:

vg = VectorGlyph(x, y, u, v, cmap='viridis')
fig, ax, artist = vg.plot(kind='quiver', title='Quiver')

vg = VectorGlyph(x, y, u, v, cmap='viridis') fig, ax, artist = vg.plot(kind='quiver', title='Quiver')

2. Streamlines¶

In [3]:

vg = VectorGlyph(x, y, u, v, cmap='cool')
fig, ax, stream = vg.plot(kind='streamplot', title='Streamlines')

vg = VectorGlyph(x, y, u, v, cmap='cool') fig, ax, stream = vg.plot(kind='streamplot', title='Streamlines')
