Plotly chart not showing in Jupyter notebook
提问by Liz
I have been trying to solve this issue for hours. I followed the steps on the Plotly websiteand the chart still doesn't show in the notebook.
几个小时以来，我一直试图解决这个问题。我按照Plotly 网站上的步骤操作，但图表仍然没有显示在笔记本中。
This is my code for the plot:
这是我的情节代码：
colorway = ['#f3cec9', '#e7a4b6', '#cd7eaf', '#a262a9', '#6f4d96', '#3d3b72', '#182844']
data = [
go.Scatter(
x = immigration.columns,
y = immigration.loc[state],
name=state) for state in immigration.index]
layout = go.Layout(
title='Immigration',
yaxis=dict(title='Immigration %'),
xaxis=dict(title='Years'),
colorway=colorway,
font=dict(family='Courier New, monospace', size=18, color='#7f7f7f')
)
fig = go.Figure(data=data, layout=layout)
iplot(fig)
And this is everything I have imported into my notebook:
这是我导入到笔记本中的所有内容：
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import plotly.plotly as py
import plotly.graph_objs as go
from plotly.offline import init_notebook_mode, iplot
init_notebook_mode(connected=True)

You need to change init_notebook_modecall, if you want to work in offline mode.
init_notebook_mode如果您想在离线模式下工作，则需要更改通话。
Such that:
这样：
# Import the necessaries libraries
import plotly.offline as pyo
import plotly.graph_objs as go
# Set notebook mode to work in offline
pyo.init_notebook_mode()
# Create traces
trace0 = go.Scatter(
x=[1, 2, 3, 4],
y=[10, 15, 13, 17]
)
trace1 = go.Scatter(
x=[1, 2, 3, 4],
y=[16, 5, 11, 9]
)
# Fill out data with our traces
data = [trace0, trace1]
# Plot it and save as basic-line.html
pyo.iplot(data, filename = 'basic-line')
Output should be shown in your jupyter notebook:
输出应显示在您的 jupyter 笔记本中：

In case you want to use Jupyter lab, you will have to install the plotly jupyterlab extension: https://github.com/jupyterlab/jupyter-renderers/tree/master/packages/plotly-extension.
