问题描述

我想检索该图中突出显示的 x 值:

I'd like to retrieve the x-values highlighted in this plot:

绘图是使用此代码段在 Jupyter Notebook 中生成的:

The plot is generated in a Jupyter Notebook using this snippet:

import plotly
import cufflinks as cf
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
import pandas as pd
import numpy as np

# setup
init_notebook_mode(connected=True)
np.random.seed(123)
cf.set_config_file(theme='pearl')

# Random data using cufflinks
df = cf.datagen.lines()

# plot
fig = df.iplot(asFigure=True, kind='scatter',xTitle='Dates',yTitle='Returns',title='Returns')
iplot(fig)

<小时>

这是我尝试过的:

使用此设置，您只需在笔记本中运行 fig 即可检索每个系列的每个 x 和 y 值.但刻度值无处可寻.

With this setup, you can retrieve every x and y value for every series by simply running fig in the notebook. But the tick values are nowhere to be found.

我也尝试过深入研究 dir(fig)，并认为 fig.axis 的输出可能会解决问题，但没有:

I'v also tried digging deeper in dir(fig), and thought maybe the output from fig.axis would do the trick, but no:

{'x1': {'gridcolor': '#E1E5ED',
  'showgrid': True,
  'tickfont': {'color': '#4D5663'},
  'title': {'text': 'Dates', 'font': {'color': '#4D5663'}},
  'zerolinecolor': '#E1E5ED'},
 'y1': {'gridcolor': '#E1E5ED',
  'showgrid': True,
  'tickfont': {'color': '#4D5663'},
  'title': {'text': 'Returns', 'font': {'color': '#4D5663'}},
  'zerolinecolor': '#E1E5ED'}}

然而，网格和刻度还有其他选项，例如 'showgrid': True 和 'tickfont'，但这些值似乎在某处隐藏"否则.

There are however other options for the grid and ticks there like 'showgrid': True, and 'tickfont', but the values seem to be "hidden" somewhere else.

有什么建议吗?

推荐答案

此数据仅在 Javascript 上下文中可用，因此很遗憾无法从 Python 访问.

This data is only available in the Javascript context, and so unfortunately is inaccessible from Python.
