The ROC curve generated when one creates a classification model in Spotfire does not have a y=x line to compare the model visually against random outcome.
While one can easily add a y=x line using the Lines and Curves properties of the ROC plot, it would be great to have that line already configured when the plot is generated.
When doing demos, I add this line manually. It'd be great to not have to do this manually in front of the audience.
