All plots show up in notebook, but nbconvert notebook to html, only latest plotly express plots show up

Question

Background

• I'm working on a data challenge with 3GB data.
• I plotted about 10 plots using ploy-express in jupyter notebook.
• I didn't use fig.show('notebook') because it didn't work.
• I used py.init_notebook_mode(), all plots show up perfectly in notebook.
• They are simple plots each with 1 year of data, like fig = px.line(df, x, y, ...) then fig.show()

Everything works fine in notebook.

Problem

But until I tried to convert notebook into HTML file, only the latest 6 plots show up.

The first 4 plots have titles, legends, axes, background-canvas, when I hover over them the numbers pop up, but plots are not showing up, and each has an unhappy square face with "x"-looking eyes.

I tried:

• !jupyter nbconvert notebook.ipynb --to html --template classic
• or with --execute
• or without --template
• I increased notebook size changing NotebookApp.max_buffer_size, this didn't work.

I suspect this is a memory limit problem on nbconvert or HTML-related, because:

• when I reduce it to 6 plots, all of them show up
• when I added more plots, the first ones start to experience this problem, as if there is a memory limit.
• I think these are nbconvert documentation, but I don't see any 'limit' or 'max' when writing to HTML?
  • (https://nbconvert.readthedocs.io/_/downloads/en/5.4/pdf/)
  • (https://nbconvert.readthedocs.io/en/latest/config_options.html)

Did anyone solve the same problem? Could someone help please?

Not Perfect Solution

• I have to click the legend then it shows up.
• But another graph disappears again.
• The total available is always 6 graphs like there is a limit of something

Answer 1

Accidentally, I found out the all plots show up when I use Firefox, so I realize this is a render problem.

It turns out the default is WegGL, and I switched to SVG, by adding render_mode='svg'.

Wala, everything is solved.

Answer 2

Just open the notebook in Jupyter-lab. From File menu select the option to export as HTML. It worked for me. I haven't found a way to make it work with nbconvert from command line. It would be good that you provide how you used render_mode='svg'. In my approach images were reduced and their java script was lost.
