transformnode properties

Table node iconThe Transform node allows you to select and visually preview the results of transformations before applying them to selected fields.

Example

stream = modeler.script.stream()
typenode = stream.findByID("id42KW3MSA94B")

node = stream.create("transform", "My node")
stream.link(typenode, node)

node.setPropertyValue("fields", ["Age", "K", "Na"])
node.setPropertyValue("formula", "Select")
node.setPropertyValue("formula_log_n", True)
node.setPropertyValue("formula_log_n_offset", 1)

node.run([])
