PCA: output csv file for Eigenvalues and eigenvectors and facilitate plot
While eigenvectors and variance ratios can be accessed via the Data Sources Panel, a more user-friendly output via optional csv files would be nice. Also, a tool to actually display the graphic of cumulated var% vs. components would facilitate the adequate selection of relevant components,

reporter Yes, let’s try this first.

Could you make the original objects (e.g. numpy arrays) available? E.g. via node.origValue() syntax?

I guess we will not implement special functionality that only serves PCA models.
Two thinks we could implement that address your issue might be:
Would that be sufficient for now?
