在 Jupyter notebook 中保存 pivottablejs 的配置答案

【问题标题】：Save configuration of pivottablejs in Jupyter notebook在 Jupyter notebook 中保存 pivottablejs 的配置
【发布时间】：2020-02-15 13:20:46
【问题描述】：

我正在使用 google Colab（服务器上的 Jupyter python notebook）来运行数据透视表。

这段代码：

pivot_ui(d1,outfile_path='pivottablejs.html')
HTML('pivottablejs.html')

在这个空白数据透视表中产生：

我可以操纵它来获得这个所需的图表：

但是当我刷新页面时，一切都会回到空白枢轴。我想要的是存储所需图表的配置，以便我可以在刷新后取回它。

我知道JavaScript 中有关于如何执行此操作的说明，但我无法弄清楚如何在 Jupyter 笔记本中执行此操作。有什么想法吗？

编辑看来我不是第一个尝试过的人：https://github.com/nicolaskruchten/jupyter_pivottablejs/issues/34，目前的设置是不可能的。

我的 hacky 解决方案

我重写了部分 pivottablejs 包以添加“复制配置”按钮。我将这段代码放在 Jupyter notebook 的早期单元格中，以便稍后可以访问该函数：

Google Colab 版本：

!pip install pivottablejs
from pivottablejs import pivot_ui
from IPython.display import HTML
from IPython.display import IFrame
import json, io

这使您可以制作图表（google colab 版本，Jupyter notebook 版本略有不同）：

pivot_cht_html(d1)

加载一个空白图表，您可以手动配置（下图已配置）。注意“复制设置”按钮：如果您按下按钮，它会复制配置的 JSON，然后您可以将其放回图表函数中，以便它运行您配置的图表：

pivot_cht_html(d1,json_kwargs="""
{
  "derivedAttributes": {},
  "hiddenAttributes": [
    ""
  ],
  "hiddenFromAggregators": [],
  "hiddenFromDragDrop": [],
  "menuLimit": 500,
  "cols": [
    "weeks"
  ],
  "rows": [],
  "vals": [
    "resurrected_90d"
  ],
  "rowOrder": "key_a_to_z",
  "colOrder": "key_a_to_z",
  "exclusions": {},
  "inclusions": {},
  "unusedAttrsVertical": 85,
  "autoSortUnusedAttrs": false,
  "sorters": {},
  "inclusionsInfo": {},
  "aggregatorName": "Average",
  "rendererName": "Line Chart"
}
""")

这远非理想...理想情况下，这应该作为 PR 添加到 pivottablejs 包中。如果我有时间，我会尝试这样做！
