An EM Spectrum widget is a labeled spectrum ruler. It shows the electromagnetic spectrum as bands and highlights one — useful for RF, optical, and sensor work.

​
When to use it

  • Show where a signal/sensor sits on the spectrum
  • Educational / RF context

Script API example

The same interactions from a dashboard script: 
// Show the spectrum panel only when relevant
widget.on('modeSwitch', 'on',  () => widget.show('spectrumView'));
widget.on('modeSwitch', 'off', () => widget.hide('spectrumView'));
