情节:如何检索主要刻度线和网格线的值? [英] Plotly: How to retrieve values for major ticks and gridlines?

问题描述

我想检索此图中突出显示的x值:

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

该图是使用以下代码段在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)

---

这是我尝试过的:

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

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.

我也尝试在dir(fig)中进行更深的挖掘，并认为也许fig.axis的输出可以解决问题，但是没有:

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'}}

不过，网格还有其他选项，例如'showgrid': True和'tickfont'在此处打勾，但是值似乎在其他位置隐藏"了.

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进行访问.

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