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')
这个空白枢轴的结果:
我可以操纵它来获得所需的图表:
但是当我刷新页面时，一切都回到了空白枢轴。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:https://github.com/nicolaskruchten/jupyter_pivottablejs/issues/34目前的设置是不可能的。
最佳答案
我的 hacky 解决方案
我重写了 pivottablejs 包的一部分以添加“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

这使您能够像这样制作图表(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!
