Spectrum
******************

The widget allows plotting spectrum data using Plotly, providing a configurable visualization of a spectrum attribute. 

The widget shows a spectrum plot based on selected indices from the spectrum attribute, with options to configure both X and Y axes independently.

Widget Settings
================

The following image shows an example of a widget setting.

It is possible to customize the widget settings from the inspector panel (in edit mode), as shown below:
