Histo Fill patterns in jupyter notebooks (>7, so jupyterlab engine)

ROOT
1

Dear all,

Are histograms fill patterns (in particular the one with hatches, i.e. 3xxx) implemented in the jsroot of a ROOT jupyter notebook? From a couple of topics in the forum or on github I had the impression that they should be, at least some of them, but in the notebook they are either not drawn, with jsroot on, or full filled histograms in the static pictures of jsroot off.

I learned recently that although the color-blind-friendly palettes and color schemes a bit help, they are not a complete solution, and I would like to add some filling pattern too, if supported on the notebooks.

Note that I use notebook version > 7, which means that the server has the jupyterlab engine. Should this be the problem, I can consider to roll back to the previous notebook engine.

Thanks,
Matteo

ROOT Version: 6.34.04, but JSROOT_7_8_1_commit446d98

Dear @malfonsi79,

thank you for reaching out. Could you please share a small code snippet to reproduce your situation?

Cheers,
