Hey @hakim89, this looks like a reasonable bug change to me 👍 Thanks for spotting it.

Regarding the linting failure - the easiest way to fix it (and make sure you don't run into future issues in sktime contributions) would be to install our pre-commit. Instructions for how to do that here. Ping me if you run into any issues though! :)

Cheers!

Thank you @miraep8. I ran pre-commit locally and pushed the white-space changes. Hopefully I did it correctly (first time contributing ). That same file (and few functions in it) might need some optimization and I might push more changes soon. Currently it fails silently to draw timeseries data into centers if the number is large.
