python - Matplotlib basemap 动画

我使用basemap在地图上绘制一些点，我想添加任何类型的动画。从字面上讲，它根本没有任何作用，只要它是一个动画，它就会很好。
这就是我现在要做的地图，

from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.animation as animation
map = Basemap(projection='robin', resolution = 'l', area_thresh = 1000.0,
          lat_0=0, lon_0=-130)
map.drawcoastlines()
map.drawcountries()
map.fillcontinents(color = 'gray')
map.drawmapboundary()
map.drawmeridians(np.arange(0, 360, 30))
map.drawparallels(np.arange(-90, 90, 30))

x,y = map(lons, lats)
map.plot(x, y, 'ro', markersize=4)


plt.show()

最佳答案

从here重新编写了一些代码以适应

from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.animation as animation
my_map = Basemap(projection='robin', resolution = 'l', area_thresh = 1000.0,
          lat_0=0, lon_0=-130)
my_map.drawcoastlines()
my_map.drawcountries()
my_map.fillcontinents(color = 'gray')
my_map.drawmapboundary()
my_map.drawmeridians(np.arange(0, 360, 30))
my_map.drawparallels(np.arange(-90, 90, 30))

x,y = my_map(0, 0)
point = my_map.plot(x, y, 'ro', markersize=5)[0]

def init():
    point.set_data([], [])
    return point,

# animation function.  This is called sequentially
def animate(i):
    lons, lats =  np.random.random_integers(-130, 130, 2)
    x, y = my_map(lons, lats)
    point.set_data(x, y)
    return point,

# call the animator.  blit=True means only re-draw the parts that have changed.
anim = animation.FuncAnimation(plt.gcf(), animate, init_func=init,
                               frames=20, interval=500, blit=True)

plt.show()
