如何将matplotlib动画转换为HTML5< video>标签 [英] How to convert matplotlib animation to an HTML5 <video> tag
问题描述
下面是matplolib动画图形的代码，并在
使用
print(ani.to_html5_video()) 获取视频的HTML代码.或者，直接保存到文件
，其中open("myvideo.html"，"w")为f:打印(ani.to_html5_video()，file = f)
说明
作为示例，请
string ="Hello \ nWorld" 如果在单元格中声明 string ，它将产生
'Hello \ nWorld' 但是如果您 print(string)，它将为您提供解释后的字符串
你好世界
Below there is the code of a matplolib animation graph and here is how to save it.
from IPython.display import HTML
import matplotlib.pyplot as plt
import matplotlib.animation
import numpy as np
t = np.linspace(0,2*np.pi)
x = np.sin(t)
fig, ax = plt.subplots()
ax.axis([0,2*np.pi,-1,1])
l, = ax.plot([],[])
def animate(i):
l.set_data(t[:i], x[:i]);
ani = matplotlib.animation.FuncAnimation(fig, animate, frames=len(t));
#HTML(ani.to_jshtml())
ani.to_html5_video()
What I basically do is copying the generated code into a basic html script like this one:
<html>
<head>
<title>Page Title</title>
</head>
<body>
<h1>My First Heading</h1>
<video width="432" height="288" controls autoplay loop> BLABLA </video>
</body>
</html>
Graph is not showing but the heading and the video menu is there. Why? How can I fix it?
Just stating ani.to_html5_video() will not give you the correct string out.
If you look closely at what you have copied, you will see linebreaks (\n) all over the output. (I marked them in the screenshot...)
Use
print(ani.to_html5_video())
to obtain the HTML code of the video. Or, to directly save to a file
with open("myvideo.html", "w") as f:
print(ani.to_html5_video(), file=f)
Explanation
As an explanatory example, take
string = "Hello\nWorld"
If you state string in the cell it will produce
'Hello\nWorld'
But if you print(string), it will give you the interpreted string
Hello
World
