PolygonGlyph¶

PolygonGlyph wraps PolyCollection. A per-polygon values array fills and colour-maps the polygons (with a colorbar); with no values or outline_only=True, only the outlines are drawn.

1. Value-filled polygons¶

In [2]:

values = np.array([10., 20., 30.])
pg = PolygonGlyph(polygons, values=values, cmap='YlGnBu')
fig, ax, pc = pg.plot(title='Filled by value')
ax.autoscale()

values = np.array([10., 20., 30.]) pg = PolygonGlyph(polygons, values=values, cmap='YlGnBu') fig, ax, pc = pg.plot(title='Filled by value') ax.autoscale()

2. Outlines only¶

In [3]:

pg = PolygonGlyph(polygons)
fig, ax, pc = pg.plot(outline_only=True, title='Outlines')
ax.autoscale()

pg = PolygonGlyph(polygons) fig, ax, pc = pg.plot(outline_only=True, title='Outlines') ax.autoscale()
