Description

There have been a couple of issues asking how to extract the underlying data for the component plots, e.g. https://github.com/facebook/prophet/issues/1920

I think it wouldn't hurt us to separate the code that calculates the data for the plots from the plotting code.

Research direction
The issue asks to separate the data calculation logic from the plotting code in Prophet. Look at the plotting functions in the Prophet repository, likely in `python/prophet/plot.py` or similar. Identify which functions compute component plot data (e.g., `plot components`, `plot seasonality`) and extract the data preparation steps into separate helper functions. Review existing comments and related issues (e.g., #1920) to understand user requests for data extraction. Ensure the refactored code maintains backward compatibility.
