Decision Tree to Image

Renders a decision tree view on an image. Currently supported image type is PNG. The data input is optional. It can be used to provide a column with color information. This color information is needed for the chart in the nodes of the decision tree.

Options

Width (in Pixel)

The width of the image.

Collapse Table

The height of the image.

Tree Scaling

To make sure that the decision tree is completely rendered on the image you would choose Shrink to image area. With Fit to image area the tree may also be scaled up to fit the image area. Finally, Fixed value gives control over the scaling magnitude.

Zoom

The scaling magnitude for the tree scaling option Fixed value.

Branch Display

With this options you can restrict the number of branches (nodes) of the tree rendered on the image. Using Unfold with data coverage, all branches will be unfolded that have a total data coverage greater than the given value. With Unfold to level, the tree will be unfolded to the given level where the root is on level 0 and its children on level 1.

Node Display

Controls the style how the nodes of the tree are displayed. You can choose to hide the table ore the chart in the nodes. Note, that the chart will show up only when the data input provides a column with color information.
