Wiggle Plot for Seismic Data Section

Wiggle Plot for Seismic Data Section

Introduction

The wiggle display is a visualization methodology for two-dimensional scalar fields on a horizontal plane. Originally developed by the geophysical community, wiggle plots provide visual analysis of seismic, seismological, or any other vibration data — helping identify events through the coherent alignment of lobes that relate to geological features and physical rock properties.

Inspired by the MATLAB wiggle function, this Python package offers a similar interface for plotting seismic section data with control over colour, amplitude, and axis orientation.

Given an M × N ndarray, wiggle decomposes it into N traces of length M (column-major, vertical mode by default).
