Hi @core-man, just reviewed your implementation of wiggle and it looks pretty good! Only a few minor comments for now. Let us know if you need help with adding a unit test, you could just adapt your gallery example into a unit test (but simplify it as much as possible, take out unnecessary arguments like frame perhaps).

Oh, and just to prevent this PR from taking up too much time (speaking from experience), please don't wrap every single alias for wiggle right now, just keep it to the bare minimum. We can complete the long alias list in a separate PR.

Oh, and please remember to add wiggle to doc/api/index.rst.

Thank you. Will Ping you when I need help. I am preparing for the job interview these two weeks. Will come back soon next week.

Good to know. I thought to wrap all the arguments in one PR.

@michaelgrund Thanks for the review.

[weiji14]

I'm happy with the def wiggle() code implementation and single unit test, and you've wrapped the main required parameter scale (Z) and a couple of other basic ones which is good. Just a few minor edits and it should be 🤞 close to merging.

I don't think wiggle is a seismology-specific module. I recommend moving the example to the "Line" category.

[core-man]

okay. @seisman done in 3f32058.

[michaelgrund]

Agree with @seisman to move the gallery example to the "Line" category since e.g. traces of active reflection seismic data are also often plotted in such way (and not only seismology related content). Except that point, I'm fine with that PR. Great work!
