multiple ROC curves in one image


I need to have multiple ROC curves from several Bayesian models (predicting the same class) in one image.

Something like this:

Is it possible to do this with some KNIME's node?

Thanks for reply :)


Sure. The ROC node can plot as many curves as you like. Just select them in the node configuration dialog.

Well I am not sure what do you mean. There are only "Columns containing the positive class probabilities".

The node's description explains in detail, how the node works.

I have got it, thanks :)

You just need to join test data passed through different Bayesian predictors and add its class probability in ROC node configuration.
