Thanks, I appreciate the answer!

So not the latter. I can always log metrics during training and visualize them.

I'm thinking of a few plots in my current in-house tooling which are slightly different than the standard charts we look at. For example a custom parallel coordinate chart that can use aggregations, categorical variables, etc.
To move over to trains, I'd like to have all these custom plots in my dashboard. I haven't tried to do them in trains yet (I'm just starting).

So my question in general is pertaining to if I would need to get better at Javascript if I were to make those changes. My guess is yes as those changes seem to be at the web UI level. Does that make sense?
