The view can be accessed either via the “Open view” action on the executed node or on KNIME Hub.\n <br />\n In the node configuration, you can choose the input data you want to display and enable certain controls, which are then available in the view. This includes the ability to choose different columns as reference and prediction columns or the possibility to set a title.\n <br />\n The configuration also offers a preview of the view, which should help to get the ROC curve in the desired shape quickly.\n <br />\n Since missing values as well as NaN (not a number) or infinite values cannot be displayed in the view, they will be omitted.
