Editing the Treatments Column Header

When developing the app, you are able to control the name of the Treatment column leaf nodes in the tree editor.

Prior to Decision Optimizer 8.3, the leaf nodes in a decision tree were always labeled Treatments. This value is now configurable. When Decision Optimizer displays a decision tree, it abides by the following rules:

  1. FJDT and PMML trees can specify what the label of their leaf nodes should be. If they do so, this value is used. (This capability is not available in FSML format trees so this step is skipped.)
  2. An app can configure the leaf node label within the tree configuration file. An optional string attribute, leafNodeLabel, holds the default leaf node label for trees using this configuration file. If set, this value is used
  3. If neither of these conditions is met, the column is labeled Treatments.

Full details of the tree configuration file are documented in the Xpress Insight Developer Guide for Mosel, in the topic Building Apps that use the Decision Tree Editor.

Note: The existing tree configuration attribute has been renamed from treatments to leafNodes, because some applications might not use the leaf nodes to represent treatments. Treatments is still supported for backwards compatibility reasons. FJDT trees brought in from another application, including old versions of Decision Optimizer, will now use the label in the tree rather than Treatments. Previous version of Decision Optimizer generated trees using a label Action, consequently all trees generated by old versions of Decision Optimizer will use the label Action rather than Treatments.
