Wiggle plots: Best way to add important distances/levels to the plot?

[fghorow]

Hi All,

I've got a wiggle plot of some DAS data that I need to mark some (externally supplied) distances in.

I've been struggling with (the obvious) grabbing of the matplotlib Figure/Axes objects and adding hlines to those in the usual fashion of matplotlib. But, puzzlingly, the distance values I supply to be marked are plotted at completely different locations from the wiggle traces.

I looked through the DASCore code ("Use The Source, Luke!"), only to find the _get_offsets_factor() function in dascore/viz/wiggle.py.

I do understand the need to do something like that for wiggle plot viz, but I was wondering if the best thing to do to accomplish my goal of visualizing levels on the same plot is to go through that exercise.

Is there some workaround where I can build up a different "patch" of my marked levels (maybe as zero amplitude traces of different color?), merge that construction with the original patch of actual data, and just call the existing viz.wiggle routine on that?

Advice from experienced folks would be greatly appreciated!

Good question. I am not terribly familiar with the wiggle plot. @aissah, do you have any ideas here?
