Bank Balance Graph

Plotting balance over time with Starling Bank's CSV export.

Features:

• combine multiple CSVs into one graph (Starling's maximum export is 1 year)
• show trend line for past N days
  • show average daily spending/earning for trend line period
  • work out estimated TUZM (Time Until Zero Money)

How to use

Requirements: Python (with matplotlib, numpy)

Export CSV with Starling.

python .\plot.py --trendline 90 .\StarlingStatement_2022-05-26_2023-05-26.csv .\StarlingStatement_2023-05-26_2023-12-12.csv

Notes

This could work with other banks. I don't know, because I don't have other banks. In principle, if their CSVs have a "date" and "balance" column then it will work. You will have to change this code to use the right CSV column and date format.
