Understanding the `cut` Function in Pandas for Custom Plotting
Understanding the cut Function in Pandas Introduction to Binning Data In data analysis and visualization, binning is a common technique used to group continuous data into discrete intervals or ranges. This process helps simplify complex data distributions by reducing them to more manageable categories. Pandas, a popular library for data manipulation and analysis in Python, provides an efficient way to perform binning using the cut function. The cut function allows us to divide a series of data into a specified number of bins, assign values from a list (or another iterable) to each bin, and return a new series with these assignments.
