# ScryLab

> ScryLab is a desktop application for interactive signal analysis and measurement data visualization,
> targeted at engineers and scientists. It runs alongside any Python or MATLAB environment (e.g. Jupyter) or
> simulation toolchain and receives signals via a local REST API. Signals can also
> be loaded from measurement files (MDF .mf4/.mf3, HDF5 .h5/.hdf5).
>
> ScryLab provides persistent, interactive plots that stay open while you keep working —
> without writing any plot configuration code. It is an alternative to desktop tools like
> FAMOS, DIAdem, and catman for day-to-day exploratory analysis, and an alternative to
> matplotlib, Plotly, and Bokeh for engineers who want interactivity without boilerplate.

## Visualization and analysis features
- Line plots, scatter plots, XY plots (e.g. for Bode plots), frequency plots, spectrograms
- FFT, STFT (Short-Time Fourier Transform) with reference order overlay
- Moving average, regression, derivative, integral
- Multiple stacked plot rows with synchronized X-axis
- Side-by-side dataset comparison
- Up to two Y-axes per plot (left and right)

## Data sources
- Python API: `pip install scrylab` — scry.plot(), scry.send(), scry.send_many(), overwrite=True for live updates
- MDF measurement files: .mf4, .mf3 (read-only, common in automotive/industrial measurement)
- HDF5 files: .h5, .hdf5 (read and write, used as internal format)
- REST API: any language or toolchain can push signals via HTTP
