A Matplotlib scale that compresses non-business days and off-hours. Every visible unit on the axis corresponds to active time — no gaps for weekends, holidays, or overnight periods. No data preprocessing needed.

**→ Full documentation at [saemeon.github.io/busdayaxis](https://saemeon.github.io/busdayaxis/)**

## Why

Time series that only evolve on business days — prices, signals, operational metrics — look distorted on a standard calendar axis: weekends and holidays introduce flat gaps that compress active periods and visually skew slopes. `busdayaxis` removes those gaps entirely.

## What it provides

- Compress weekends, holidays, and overnight gaps with a single `set_xscale("busday")` call
- Per-day session hours (`bushours`) — uniform, per-weekday list, or dict with sensible defaults
- Custom weekmasks and holiday lists, compatible with NumPy's busday calendar
- `BusdayLocator` to filter ticks to business hours and days only
- Implemented as a proper `ScaleBase` subclass — autoscaling, shared axes, and all standard artists work without any changes to your plotting code

## Installation

```bash
pip install busdayaxis
```

## Quick Start

```python
import matplotlib.pyplot as plt
import busdayaxis

busdayaxis.register_scale()  # register once at the start of your script

fig, ax = plt.subplots()
ax.plot(dates, values)
ax.set_xscale("busday")  # compress weekends (Mon–Fri default)
```
