Overlaying Plots Using Matplotlib in KNIME

This workflow demonstrates creating overlaying plots using matplotlib python package in Python Script node. In this example, a histogram is created of 20 bins and is overlayed with a frequency polygon. This frequency polygon connects mid-points of each interval, portraying the shape of distribution followed by the numerical column.
