Question

我有一个简单的python动画程序，我下载了。我正在改变它以更好地理解动画调用。该程序在屏幕上以圆圈形式进行简单的点移动。我放置了改变点位置和动画调用的函数。那没关系。然后我把图的定义放到一个类中。这也行得通。这是它的外观，

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

class FIG:
    def __init__(self):
        self.fig=plt.figure()
        self.ax = self.fig.add_subplot(111)
        self.line, = self.ax.plot([], [], 'bo', ms=10)
        self.ax.set_ylim(-1, 1)
        self.ax.set_xlim(-1, 1)
class sD:    
    def simData(self):
        t_max = 100.0
        dt = 0.001
        x = 0.0
        t = 0.0
        while t < t_max:
            x = np.sin(np.pi*t)
            t = t + dt
            y = np.cos(np.pi*t)
            yield x, y
class sP:
    def simPoints(self,simData):
        x, t = simData[0], simData[1]
        f1.line.set_data(t, x)
        return f1.line #line2#, time_text

f1=FIG()
sd=sD()
sp=sP()

ani = animation.FuncAnimation(f1.fig, sp.simPoints, sd.simData, blit=False,
     interval=10, repeat=True)

plt.show()

现在，我想通过动画调用将图形实例作为参数传递。但它不起作用，这是新的代码不起作用....

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

class FIG:
    def __init__(self):
        self.fig=plt.figure()
        self.ax = self.fig.add_subplot(111)
        self.line, = self.ax.plot([], [], 'bo', ms=10)
        self.ax.set_ylim(-1, 1)
        self.ax.set_xlim(-1, 1)
class sD:    
    def simData(self):
        t_max = 100.0
        dt = 0.001
        x = 0.0
        t = 0.0
        while t < t_max:
            x = np.sin(np.pi*t)
            t = t + dt
            y = np.cos(np.pi*t)
            yield x, y
class sP:
    def simPoints(self,simData,figg):
        x, t = simData[0], simData[1]
        figg.line.set_data(t, x)
        return figg.line #line2#, time_text

f1=FIG()
sd=sD()
sp=sP()

ani = animation.FuncAnimation(f1.fig, sp.simPoints, sd.simData, f1, blit=False,
     interval=10, repeat=True)

plt.show()

编译器告诉我，

self._drawn_artists = self._init_func()
AttributeError: FIG instance has no __call__ method

任何评论都表示赞赏。感谢

python动画......传递一个参数
