How Can I Plot Multiple Alpha Values in Cosmology Using Python?

Click For Summary
SUMMARY

This discussion focuses on plotting multiple alpha values in cosmological simulations using Python. The user is solving the Friedmann equation with quintessence, utilizing a scalar field potential of the form x^(-alpha). Recommendations include using the matplotlib library for creating plots, which offers various options for visualizing different alpha values with annotations. The user seeks guidance on implementing this without sharing their code.

Hello!
I've been working on a code that solves the Friedmann equation with quintessence using a scalar field potential of the form x^(-alpha) where alpha is a free parameter. I would like to plot different values of alpha in the same plot with annotations for each. For now, my code has initial values, then a time evolution loop for the differential equations and then the plots. How do I do this? I'd prefer getting answers without me having to paste the code.
Thanks!
