Spinmob is a scientific data analysis and plotting package I wrote to escape expensive, buggy, poorly-documented programs like Origin, expensive "licensey" programs like Matlab, and weaker programs like Excel. It turns out python is just better than everything else, and it behaves the same on all computers for free. Ultimately, this, the packages it relies on, and Inkscape are all we needed to take, analyze, visualize, and publish our data.

The main features are

• forgiving and user-friendly data class for handling ASCII data files
• high-level automated plotting based on matplotlib
• interactive nonlinear least-squares multi-curve fitting object
• a simplified GUI library with high-level objects based on pyqtgraph
• a bunch of random functions I found useful in dealing with strings and data.
