python - Matplotlib basemap 多个形状动画异常: 'list' object has no attribute 'set_animated'

我正在使用 basemap 在 map 上绘制一些多边形并制作动画。当我为一个多边形设置动画并更改其形状时,它就会起作用。如果我添加第二个,我会遇到异常:

Traceback (most recent call last):
File "...\Programs\Python\Python37\lib\site-packages\matplotlib\cbook\__init__.py", line 216, in process
func(*args, **kwargs)

self._init_draw()

a.set_animated(self._blit)
AttributeError: 'list' object has no attribute 'set_animated'

我的代码:

input = pd.read_csv(filename)
data = pd.read_csv(datafilename)


m = Basemap(projection='spstere',boundinglat=-50,lon_0=0,resolution='l', area_thresh = 1000.0)
m.fillcontinents()
m.drawmapboundary()
lon =[]
lat = []
lon1=[]
lat1=[]
for j in range(0,100):
latlist = list()
latlist1 = list()
for i in range(0,361):
latlist.append(float(input.iloc[j][str(i)]))
latlist1.append(float(data.iloc[j][str(i)]))
lat.append(latlist)
lon.append(list(range(0,361)))
lat1.append(latlist1)
lon1.append(list(range(0,361)))
polys = []

x,y = m(lon[0],lat[0])
xy = list(zip(x,y))
poly=Polygon(xy,facecolor='None', alpha=1, edgecolor='green', linewidth=1)

x1,y1 = m(lon1[0],lat1[0])
xy1 = list(zip(x1,y1))
poly1=Polygon(xy1,facecolor='None', alpha=1, edgecolor='red', linewidth=1)

polys.append(poly)
polys.append(poly1)
def init():
plt.gca().add_patch(polys[0])
plt.gca().add_patch(polys[1])
return polys,

def animate(i):
print(i)
x,y = m(lon[i], lat[i])
xy=list(zip(x,y))
polys[0].set_xy(xy)

x1,y1 = m(lon1[i], lat1[i])
xy1=list(zip(x1,y1))
polys[1].set_xy(xy1)
return polys,

anim = animation.FuncAnimation(plt.gcf(), animate, init_func=init, frames=100, interval=500, blit=True)

plt.show()

如果我在函数中只返回一个多边形并设置 blit=False ,它就会起作用。如果我在函数中只返回一个多边形并且 blit=True - 只有一个多边形发生变化。如何使用位图传输在一个动画中制作两个形状的动画?

最佳答案

您需要返回一个您想要更新的艺术家迭代。这通常是一个元组或列表。

polys 是艺术家列表
poly, poly1 是艺术家的元组
[poly, poly1] 是艺术家列表
(poly, poly1) 是艺术家的元组
等等

但是polys, 是一个列表的元组。该错误告诉您,该列表不是艺术家。
