我想在 y 轴上为矩形内的颜色设置动画,颜色填充应该像 peakmeter 条的行为方式一样上下移动。这段代码中有我无法解决的错误。请帮我解决这个问题。
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import random
import numpy
class AnimRect(object):
'''Animate a rectangle'''
def __init__(self):
self.fig = plt.figure(figsize = (5,5))
# create the axes
self.ax = plt.axes(xlim=(0,100), ylim=(0,100), aspect='equal')
# create rectangle
self.rect = plt.Rectangle((0,0), 5, 50,
fill=True, color='gold', ec='blue')
self.ax.add_patch(self.rect)
self.y=[]
for i in range(100):
x = random.randint(0, 30)
self.y.append(x)
self.y = numpy.array(self.y)
# print(self.y,len(self.y))
self.call_animation()
plt.show()
# animation function
def animate(self, i):
self.rect = self.ax.fill_between(0, self.y[i],0, color = 'red')
return self.rect,
def call_animation(self):
# call the animator function
self.anim = animation.FuncAnimation(self.fig, self.animate, frames=len(self.y), interval=0.1, blit=True, repeat=False)
def main():
rect = AnimRect()
main()
它在控制台中给出了这样的错误
idx, = np.nonzero(mask[:-1] != mask[1:]) IndexError: too many indices for array
