如何在jupyter / ipython笔记本中显示图旁边的文本段落 [英] How to display a text paragraph next to figure in jupyter/ipython notebook

问题描述

我正在寻找一种（可能是创造性的）方式将文本放在jupyter笔记本中的图形旁边。我们的想法是对图表进行详细描述，而不是通常的笔记本垂直流程。

I am looking for a (perhaps creative) way to place text next to a graph in the jupyter notebook. The idea is to have a detailed description of the chart, right next to it, instead of the usual vertical flow of the notebook.

任何想法？

推荐答案

一种颇具创造性的方法是模仿内联后端，但添加基础表。 python 2.7的一个可能的解决方案看起来像

A rather creative way is to mimic the inline backend but adding a underlying table. A possible solution for python 2.7 could look like

from io import BytesIO
import matplotlib.pyplot as plt
from IPython.display import display, Image, HTML
import base64

def plotdesc(fig, text, iwidth=None):
    bio = BytesIO()
    # save fig as png to bytes IO instead to disk
    fig.savefig(bio, format='png')
    plt.close(fig)
    iwidth = ' width={0} '.format(iwidth) if iwidth is not None else ''
    img_tag = "<img src='data:image/png;base64," + base64.b64encode(bio.getvalue()) + "'{0}/>".format(iwidth)
    datatable = '<table><tr><td>{0}</td><td>{1}</td></tr></table>'.format(img_tag, text)
    display(HTML(datatable))

用作：

fig, ax = plt.subplots(1,1, figsize=(6,4))
ax.plot([1,2,3])
text = '<h4>Description of the chart:</h4><BR>asdfsa fasdf qwer fsdaf er qw asdcdsafqwer dacfas dfqwetr cvxy fsa'
plotdesc(fig, text, iwidth='500px')

如果你现在将表格CSS设置为删除边框例如

If you now set the table CSS to remove the border e.g.

%%html
<style>
table,td,tr,th {border:none!important}
</style>

你得到的情节如

you get a plot like

当然这个解决方案可以进一步增强以使用固定的列宽等。
IIRC base64编码与python 3.x略有不同。

Of course this solution can be further enhanced to use fixed column widths, etc. IIRC the base64 encoding was slightly different with python 3.x.
