我目前正在使用Jupyter笔记本，我想通过HTML渲染SVG，而不将它们保存为本地SVG，然后再显示它们。
我正在使用此代码：
%matplotlib inline
from IPython.display import SVG, HTML
html_pygal = """
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="http://kozea.github.com/pygal.js/javascripts/svg.jquery.js"></script>
<script type="text/javascript" src="http://kozea.github.com/pygal.js/javascripts/pygal-tooltips.js"></script>
<!-- ... -->
</head>
<body>
<figure>
{pygal_render}
</figure>
</body>
</html>
"""
import pygal
line_chart = pygal.Line()
line_chart.title = 'Browser usage evolution (in %)'
line_chart.x_labels = map(str, range(2002, 2013))
line_chart.add('Firefox', [None, None, 0, 16.6, 25, 31, 36.4, 45.5, 46.3, 42.8, 37.1])
line_chart.add('Chrome', [None, None, None, None, None, None, 0, 3.9, 10.8, 23.8, 35.3])
line_chart.add('IE', [85.8, 84.6, 84.7, 74.5, 66, 58.6, 54.7, 44.8, 36.2, 26.6, 20.1])
line_chart.add('Others', [14.2, 15.4, 15.3, 8.9, 9, 10.4, 8.9, 5.8, 6.7, 6.8, 7.5])
HTML(html_pygal.format(pygal_render=line_chart.render()))
问题在于：当Jupyter设法渲染SVG文件时，它也会显示一个Javascript错误，如下所示：
B'\ n
* SVG图片来到这里
” Javascript错误添加输出！ SyntaxError：非法字符 有关更多详细信息，请参阅浏览器Javascript控制台。
检查浏览器控制台时，这是错误消息：

我的Python版本： 3.6.0 操作系统：Windows 7 64位 Pygal版本：2.3.1
注意：我当前的解决方法有效但不是我正在寻找的解决方案是创建一个本地SVG，然后使用库导入显示它：from IPython.display import display
答案 0 :(得分：3)
我的解决方案：
import pygal
from IPython.display import SVG, display
bar_chart = pygal.Bar()
bar_chart.add('Fibonacci', [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55])
display(SVG(bar_chart.render(disable_xml_declaration=True)))
答案 1 :(得分：2)
更好：
bar_chart = pygal.Bar()
bar_chart.add('Fibonacci', [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55])
display({'image/svg+xml': bar_chart.render()}, raw=True)
答案 2 :(得分：1)
所有答案都显示了小部件，但没有工具提示，我找到了包括它们的方法（我从他们的网站“借用”了它）：
import pygal
from ipywidgets import HTML
import base64
line_chart = pygal.Line()
line_chart.title = 'Browser usage evolution (in %)'
line_chart.x_labels = map(str, range(2002, 2013))
line_chart.add('Firefox', [None, None, 0, 16.6, 25, 31, 36.4, 45.5, 46.3, 42.8, 37.1])
line_chart.add('Chrome', [None, None, None, None, None, None, 0, 3.9, 10.8, 23.8, 35.3])
line_chart.add('IE', [85.8, 84.6, 84.7, 74.5, 66, 58.6, 54.7, 44.8, 36.2, 26.6, 20.1])
line_chart.add('Others', [14.2, 15.4, 15.3, 8.9, 9, 10.4, 8.9, 5.8, 6.7, 6.8, 7.5])
b64 = base64.b64encode(line_chart.render())
src = 'data:image/svg+xml;charset=utf-8;base64,'+b64
HTML('<embed src={}></embed>'.format(src))
答案 3 :(得分：0)
尝试在渲染中使用“is_unicode = True”，如下所示：
HTML(html_pygal.format(pygal_render=line_chart.render(is_unicode=True)))
