histogramnode properties

Last updated: Feb 12, 2025

Histogram node icon 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)
