Matplotlib动画在Colab中显示不正确
Matplotlib动画在Colab中显示不正确
提问于 2022-04-15 02:13:41
我知道以前有这个问题的答案，但出于某种原因，我似乎无法让动画展示。相反，动画的所有帧都被覆盖在一个出现在空白动画下面的图形中。
from matplotlib import animation
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
import random
from matplotlib import rc
rc('animation', html='jshtml')
# This is setup code
class_capacity = [100, 100, 100]
classes = ["CS1301", "CS1331", "CS1332"]
current_enrolled_students = [10, 0, 0]
fig, axes = plt.subplots(figsize=(8,6))
#axes =fig.add_subplot()
axes.set_ylim(0, 100)
cmap = plt.get_cmap("jet")def animate(i):
axes.clear()
axes.set_ylim(0, 100)
for i in range(len(current_enrolled_students)):
current_enrolled_students[i] = random.randint(0, class_capacity[i])
barlist = plt.bar(classes, current_enrolled_students)
for i in range(len(barlist)):
barlist[i].set_color(cmap(current_enrolled_students[i] / class_capacity[i]))ani = FuncAnimation(fig, animate, interval=400, blit=False, frames=9, repeat=False)
#plt.close()
#plt.show()
ani我试图复制一个与这里类似的项目
我很确定这个错误是小的，但我不知道问题到底出在哪里。任何帮助都是非常感谢的。

我认为原因是在动画功能中使用了plt.bar。我认为将其更改为axes.bar()并关闭初始图形将完成动画。
from matplotlib import animation
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
import random
from matplotlib import rc
rc('animation', html='jshtml')
# This is setup code
class_capacity = [100, 100, 100]
classes = ["CS1301", "CS1331", "CS1332"]
current_enrolled_students = [10, 0, 0]
fig, axes = plt.subplots(figsize=(8,6))
#axes =fig.add_subplot()
axes.set_ylim(0, 100)
cmap = plt.get_cmap("jet")
def animate(i):
axes.clear()
#axes.set_ylim(0, 100)
for i in range(len(current_enrolled_students)):
current_enrolled_students[i] = random.randint(0, class_capacity[i])
barlist = axes.bar(classes, current_enrolled_students)
for i in range(len(barlist)):
barlist[i].set_color(cmap(current_enrolled_students[i] / class_capacity[i]))
ani = FuncAnimation(fig, animate, interval=400, blit=False, frames=9, repeat=False)
plt.close()
#plt.show()

我也有同样的问题。感谢Kalibril，我可以在colab上运行动画。
import matplotlib.animation
import matplotlib.pyplot as plt
from itertools import count
import random
plt.rcParams["animation.html"] = "jshtml"
plt.rcParams['figure.dpi'] = 150
plt.ioff()
fig, ax = plt.subplots()
x_value = []
y_value = []
index = count();
def animate(t):
x_value.append(next(index))
y_value.append(random.randint(0,10))
ax.cla()
ax.plot(x_value,y_value)
ax.set_xlim(0,10)
