Uncaught ReferenceError: Plotly is not defined

I am trying to create plots from jupyter kernel (based on ProcessMetaKernel) and display plots in jupyter notebook.

My Jupyter kernel code is

class MyKernel(ProcessMetaKernel):
def do_execute_direct(self, code, silent=True):
import plotly
import plotly.graph_objs as go
plot_div=plotly.offline.plot({"data": [go.Scatter(x=[1, 2, 3, 4], y=[4, 3, 2, 1])],"layout":
go.Layout(title="hello world")}, auto_open=False, output_type='div',include_plotlyjs=True)
self.Display(HTML(data=plot_div))
return code

Hi @maddukurisrinivasarao,

For inline display in the classic JupyterNotebook, it doesn't work to load plotly.js using a <script> tag (which is what include_plotlyjs=True does), instead it seems to be necessary to load plotly.js using requirejs. This is what the built-in offline.iplot function does.

Take a look at the HtmlRenderer/NotebookRenderer at

plotly.py/plotly/io/_base_renderers.py

Line 222 in 7cce283

class HtmlRenderer(MimetypeRenderer):

for details. You may be able to borrow some of this logic for your custom kernel.

Hope that helps!

Hi - we are currently trying to tidy up Plotly's public repositories to help us focus our efforts on things that will help users most. Since this issue has been sitting for several years, I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our backlog. Thanks for your help - @gvwilson
