The Histogram node shows the occurrence of values for numeric
fields. It's often used to explore the data before manipulations and model building. Similar to the
Distribution node, the Histogram node frequently reveals imbalances in the data.
Example
stream = modeler.script.stream()
typenode = stream.findByID("id42KW3MSA94B")
node = stream.create("histogram", "My node")
stream.link(typenode, node)
# "Plot" tab
node.setPropertyValue("field", "Drug")
node.setPropertyValue("color_field", "Drug")
node.setPropertyValue("panel_field", "Sex")
# "Options" tab
node.setPropertyValue("range_mode", "UserDefined")
node.setPropertyValue("range_min", 1.0)
node.setPropertyValue("range_max", 100.0)
node.setPropertyValue("num_bins", 10)
node.setPropertyValue("normalize", True)
node.setPropertyValue("separate_bands", False)
