The Distribution node shows the occurrence of symbolic
(categorical) values, such as mortgage type or gender. Typically, you might use the Distribution
node to show imbalances in the data, which you could then rectify using a Balance node before
creating a model.
Example
stream = modeler.script.stream()
typenode = stream.findByID("id42KW3MSA94B")
node = stream.create("distribution", "My node")
stream.link(typenode, node)
# "Plot" tab
node.setPropertyValue("plot", "Flags")
node.setPropertyValue("x_field", "Age")
node.setPropertyValue("color_field", "Drug")
node.setPropertyValue("normalize", True)
node.setPropertyValue("sort_mode", "ByOccurence")
node.setPropertyValue("use_proportional_scale", True)
