[英]Matplotlib Basemap animation
我正在使用底圖在地圖上繪制一些點,我想為它添加任何類型的動畫。 它根本沒有任何用處,只要它是動畫就會很好。
這就是我目前制作地圖所需要的,
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()
從這里重做一些代碼以適合
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()
