The Web node illustrates the strength of the relationship between values of two or
more symbolic (categorical) fields. The graph uses lines of various widths to indicate connection
strength. You might use a Web node, for example, to explore the relationship between the purchase of
a set of items at an e-commerce site.
Example
stream = modeler.script.stream()
typenode = stream.findByID("id42KW3MSA94B")
node = stream.create("web", "My node")
stream.link(typenode, node)
# "Plot" tab
node.setPropertyValue("to_field", "Drug")
node.setPropertyValue("fields", ["Sex", "BP", "Cholesterol", "Drug"])
node.setPropertyValue("true_flags_only", False)
node.setPropertyValue("line_values", "Absolute")
node.setPropertyValue("strong_links_heavier", True)
# "Options" tab
node.setPropertyValue("max_num_links", 300)
node.setPropertyValue("links_above", 10)
node.setPropertyValue("num_links", "ShowAll")
node.setPropertyValue("discard_links_min", True)
node.setPropertyValue("links_min_records", 5)
node.setPropertyValue("weak_below", 10)
node.setPropertyValue("strong_above", 19)
node.setPropertyValue("link_size_continuous", True)
node.setPropertyValue("web_display", "Circular")

Specify a threshold type. |
show_legend
|
boolean | You can specify whether the legend is displayed. For plots with a large number of fields, hiding the legend may improve the appearance of the plot. |
labels_as_nodes
|
boolean | You can include the label text within each node rather than displaying adjacent labels. For plots with a small number of fields, this may result in a more readable chart. |
