Plotly after 6.0.0 changes how fig.write_image saves plots to PDF, JPG etc

šŸ“Š Plotly Python

I was happy with the way Plotly saved PDFs when I was using this environment:

  • Python 3.13.2 and 3.13.5

  • Plotly 6.0.0

  • kaleido 0.2.1

However, things have changes when using later versions of Plotly and the newer Kaleido library:

  • Python 3.13.2 and 3.13.5

  • Plotly 6.1.1 and 6.3.0

  • kaleido 1.0.0

The output generated using write_html looks great in both environments, whereas the PDF outputs are now scrambled and the plots and text labels all over the place.

Is there something Iā€™m expected to change when using write_image in the latest Plotly versions? Thanks

(Iā€™m using a Mac M4 mini with Sequoia 15.6.1)

Hi @spiky,

Could I trouble you for screenshots or the example PDFs? And even a code snippet might be helpful.

Thanks!

Hi @ajp ,

Thank you for coming back to me so quickly !!

While getting a code sample for you, I worked out that with newer Plotly versions, write_image defaults to using the height and width of a single page size.

Whereas in Plotly 6.0.0 write_image defaults to using the Plotly Figure height and width settings.

The only change I made to get it working again was to specify the height and/or width settings in my write_image calls e.g.:

fig.write_image(file=filename, format=file_format, height=height, width=width)

Thanks again.
