## What it is
finplot is a performant Python library for plotting financial data like candlestick charts, built on pyqtgraph. It is designed for backtesting workflows with sensible defaults, real-time updates, and support for hundreds of thousands of datapoints.

## Use cases
- plot candlestick charts for stocks or crypto in python
- visualize backtesting results with fast charts
- show real-time price updates and orderbook data
- plot indicators like MACD, RSI, and volume profile
- view hundreds of thousands of financial datapoints smoothly
- create multi-chart financial dashboards with synced time axis

## When to choose
- you need fast, interactive desktop financial charts in Python
- you are doing backtesting and want opinionated defaults
- you need real-time chart updates for trading analysis
- web-based plotting like plotly is too slow for your data volume

## When to avoid
- you need charts embedded in a web app or browser
- you work in Jupyter Labs
- you want to build a user-facing exchange or trading UI
- you need static publication-quality matplotlib figures
