TheLineBaseWidget just usesplot, similar to theSliceWidget, but without spinboxes. It is used as base by the following classes.
TheLineWidget uses theShapes layer to plot intensities from a selected Image layer. So far, it only works with the shapeline. I had to makea small change inbase because ofthis line. I am using thebezier_curve from scikit-image to get pixel coordinates. There is no interpolation in this current implementation.
TheFeaturesLineWidget is similar to theFeaturesScatterWidget, but it has a third dropdown to group plots by a 'label' column.

I provided 3 minimal examples and gifs to show how it looks like. I believe theFeaturesLineWidget gets interesting, for example, when one has features over time. It also works for single time points, although I think a scatter plot would make more sense then.

I am particularly interested in using the LineWidget and the FeaturesLineWidget in other plugins I am working on.

Lastly, I tried to make them minimal and generalizable, but I have some difficulties setting what is minimal 😅 . I think I can count on your experience to help me there.

Best,
Marcelo

Thanks for the clear description, examples and gifs! I like both these a lot, and the code looks good too 👍 . I think I will need to do more thinking about theLineWidget, so would you be happy to put the base widget at theFeaturesLineWidget in a separate PR? I think I could review/merge/release that fairly quickly, without discussions about theLineWidget holding it up.
