Proper display of Altair charts when exporting to PDF
See original GitHub issueI have a Jupyter Notebook which has Altair charts in it for data visualisation. What I would like to do is to export the Notebook together with the charts to PDF using nbconvert. However, since Altair charts are JavaScript rendered, the exported document displays only alt.Chart(...) instead. Do you have any suggestions on how to set it up properly without having to export the chart to an image format and pasting it in the notebook?

Ok, I found this to be an issue with the way inkscape exports to PDF. A solution would be to overwrite the default inkscape command used by nbconvert to include a
-Dflag which ensures the exported area is the entire drawing:jupyter nbconvert --to pdf --SVG2PDFPreprocessor.command="inkscape {from_filename} --export-pdf=\"{to_filename}\" -D" <your_notebook_name>Tested with inkscape 0.92.1, the 1.0 version might have different flags.
following these suggestions, I got a version that’s fully working too.
here’s a description of the process from end-to-end if anyone finds this thread too: https://github.com/andyreagan/papermill-altair-pdf
