 BEC Widgets is built on top of the [BEC](https://bec.readthedocs.io/en/latest/) package, which provides the backend for beamline experiment control. BEC Widgets is a client of BEC, meaning it can interact with the backend through a client-server architecture. To make full usage of the available features of BEC, we recommend to check the documentation about [data access](https://bec.readthedocs.io/en/latest/developer/data_access/data_access.html) in which the messaging and event system of BEC is described.

The `Waveform` widget allows user to submit a fit request to BEC's [DAP server](https://bec.readthedocs.io/en/latest/developer/getting_started/architecture.html) choosing from a selection of [LMFit models](https://lmfit.github.io/lmfit-py/builtin_models.html#) to fit monitored data sources.
