Hey,

I am trying to use the confusion matrix (by `wandb.plot.confusion_matrix`). The proper table is logged, and I am also having the right panel in the run page.

Now, I have runs from multiple sources and I would like to group the results of these runs within the plot. I have seen that this option is available in wandb/confusion\_matrix/v2. I went into the editor and add the correct config field that holds the “source” (just source name) But I could not group by that name (I can choose the “source” key in the right panel but could not get the data plotted)

I was suspecting the name filter there, But I could not understand what the name is used for.

Some help about what to do here would be really appreciated 😊 😊

Hello,

I had successfully created ~2d ago a new schema for the specific need based on what presented.  
I used the v1 of the same scheme using groupby in the run selector, and added that later on to a separate report than the main workspace.

Thanks for the help!
