The Collection node shows the distribution of values for one
numeric field relative to the values of another. (It creates graphs that are similar to histograms.)
It's useful for illustrating a variable or field whose values change over time. Using 3-D graphing,
you can also include a symbolic axis displaying distributions by category.
Example
stream = modeler.script.stream()
typenode = stream.findByID("id42KW3MSA94B")
node = stream.create("collection", "My node")
stream.link(typenode, node)
# "Plot" tab
node.setPropertyValue("three_D", True)
node.setPropertyValue("collect_field", "Drug")
node.setPropertyValue("over_field", "Age")
node.setPropertyValue("by_field", "BP")
node.setPropertyValue("operation", "Sum")
node.setPropertyValue("color_field", "Drug")
node.setPropertyValue("panel_field", "Sex")
# "Options" tab
node.setPropertyValue("range_mode", "Automatic")
node.setPropertyValue("range_min", 1)
node.setPropertyValue("range_max", 100)
node.setPropertyValue("bins", "ByNumber")
node.setPropertyValue("num_bins", 10)
node.setPropertyValue("bin_width", 5)
