The deviation is the root node. Below it are the conditions that contribute to it, each with its share of the contribution as a bar and a percentage and the evidence used by the model, and below those the conditions that contribute to them. The component displays the analysis as it was produced; it does not rank or prune the causes itself. Selecting a node raises the nodeSelect event, where the application can open the underlying data and record whether the engineer agreed with the result.
Use Tab to focus the tree. The up and down arrow keys move between nodes, the left and right arrow keys collapse and expand a node, and Enter selects it.
The maxDepth property limits how many levels of the tree are expanded. A node at the limit shows no expander. This is useful on a screen that has room for the first two levels and a link to the full analysis.
