Create a Scalar Chart in Weights & Biases using python

Question

I'm using weights & biases and try to log some scalars using python SDK for W&B, the logs appear like that: a plot with a single dot I get

So I basically just run this: wandb.log({"loss": 0.5})

And looks weird, In the UI there's an opttion of creating a Scalar Chart, that you can create by pressing "add panel" and then choose "scalar chart". It looks like this: Scalar Chart made in W&B UI

So I'd like to know if there's a way of creating these scalar charts programmatically using SDK for python?

Answer 1

You can't programmatically trigger Scalar charts in the W&B workspace, but you can log them programmatically to W&B Reports

https://docs.wandb.ai/guides/reports/edit-a-report

See the ScalarChart class in this colab for how to log to it

Hope this helps!
