CV add-ons: peak finding, plotting

[p2jones]

In my fork, I've added functionality to cv.py:

• get_peaks(): returns a DataFrame of peak positions and heights, and other info from scipy find_peaks. The function also finds a peak at the upper voltage limit. I'm not sure how to best solve this.
• plot(): plots the CV, including peaks, arrows showing scan direction. It can convert units as well, and includes correct units in the axis labels.

I need to update get_peaks() to work also for all cycles in one go.

Hi @p2jones this is a really old thread. However, I actually have a need for peak detection, and specifically tracking peaks (and peak amplitude) over cycles. Wondering if you ever finalized get_peaks

[p2jones]

It worked well enough for me, and I could track peak positions and amplitudes over cycles. I just pushed some additional changes but those are related to plotting functions.
