Pygal在Jupyter筆記本中呈現SVG

我目前使用Jupyter筆記本，並且希望通過HTML呈現SVG，而不是將它們保存爲本地SVG並在之後顯示它們。使用此代碼Pygal在Jupyter筆記本中呈現SVG

林：

%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()))

這裏的問題是：雖然Jupyter設法使SVG文件還顯示JavaScript錯誤，它看起來像如下：

我的Python版本：3.6.0 操作系統：Windows 7 64位 Pygal版本：2.3.1

注意：我當前的解決方法，但不是我正在尋找的解決方案是創建一個本地SVG，然後顯示它與庫導入：from IPython.display import display

對於多一點澄清：它顯示Jupyter筆記本電腦的SVG，但我想擺脫的javascript用於演示目的的錯誤消息。 – MBUser

嘗試你SE「is_unicode =真」裏面呈現，就像這樣：

HTML(html_pygal.format(pygal_render=line_chart.render(is_unicode=True)))

更妙的是：

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)
