Cylinder: Qabs vs Diameter
==========================

This example demonstrates how to compute and visualize the scattering efficiency (Qsca) as a function of diameter for cylindrical scatterers using PyMieSim.

Measuring the scattering efficiency (Qsca)
Note: The original request mentioned Qsca, but the measurement code uses Qabs.
If Qsca measurement is intended, ensure to use the correct measure object from PyMieSim.

.. code-block:: Python

    dataframe = experiment.get('Qabs')  # Assuming Qabs was intended, replace with measure.Qsca if needed
