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.


Configure the Python Script node for visualisationsThe Python Script node can be provide with a table or an object as inputport and it can output a table, object or an image based on the user'sselection of portsStep 1: Drag the Python Script node to KNIME Analytics PlatformStep 2: Click on the three dots on the node to add an image output portStep 3: Write your script in the "Script" and import the matplotlib package tocreate overlaying and press "execute script" to check if the execution wassuccessful. Adopting Python Bundled Packages : Download and open this workflow to auto-install requirements and execute the Python scripts. This workflow uses a node from KNIMEPython Integration, which installs Python and a number of pre-defined packages on your system. Supported on KNIME Analytics Platform4.7 or higher.
