绘图不显示

Question

我只是在尝试绘图/破折号，当我编写下面的代码时，什么都没有显示.. 它只是一个空白框。我已经尝试安装nodejs（我正在使用anaconda），以便我可以尝试安装一些扩展程序'jupyter labextension install @jupyterlab/plotly-extension'，但这由于某种原因我什至无法安装nodejs。

import dash

import dash_core_components as dcc

import dash_html_components as html

import plotly.offline as pyo

import plotly.graph_objs as go

# Set notebook mode to work in offline

pyo.init_notebook_mode()

#init_notebook_mode(connected=True)

# 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]

layout=go.Layout(barmode='stack')

fig=go.Figure(data=data, layout=layout)

# Plot it and save as basic-line.html

pyo.iplot(fig, filename = 'basic-line')

我还能做些什么来帮助查看我的图表？

Answer 1

我想要更多关于 polty、Jupyterlab 等版本的信息，但iplot()很可能是这里的问题。尝试另一个基本示例，例如：代码：import plotly.graph_objects as goanimals=['giraffes', 'orangutans', 'monkeys']fig = go.Figure(data=[    go.Bar(name='SF Zoo', x=animals, y=[20, 14, 23]),    go.Bar(name='LA Zoo', x=animals, y=[12, 18, 29])])# Change the bar modefig.update_layout(barmode='stack')fig.show()阴谋：让我知道这对你有什么影响。

你可以试试这个 Google Colab 已经给出了重新分级 Plotly 的指令def configure_plotly_browser_state():&nbsp; import IPython&nbsp; display(IPython.core.display.HTML('''&nbsp; &nbsp; &nbsp; &nbsp; <script src="/static/components/requirejs/require.js"></script>&nbsp; &nbsp; &nbsp; &nbsp; <script>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; requirejs.config({&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; paths: {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; base: '/static/base',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; plotly: 'https://cdn.plot.ly/plotly-1.5.1.min.js?noext',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp; &nbsp; &nbsp; </script>&nbsp; &nbsp; &nbsp; &nbsp; '''))调用此函数 configure_plotly_browser_state()
