I am trying to plot an "ROC" curve. A simple ordered list of (X,Y) pairs, 1 line per model ID. This works fine if the model ID is on a shelf, but without it the end of the line at (1,1) connects back to (0.0).
I have tried creating a custom field to set a specific drawing order (model_id*100 - threshold*10) but that also fails to prevent the path from circling back.
Is there a way to get the three lines in one pane without the connection from (1,1) to (0.0)?
