Are there any operatores that can help me draw ROC curve?

I only get many pairs of true_positive_rate value and false positive rate value as following, 

I want to get ROC curve and AUC. Can your extension implement these two functions. The dataset and the process XML are in file.zip.

    I can get the ROC curve in the Visualizations of RapidMiner. Can I get the AUC from Visualizations of RapidMiner.
    The picture of the result in the Visualizations of RapidMiner  is as following.

    Hi @liming,

    If you want absolutely calculate the AUC from the FPR and TPR, here a process which performs this task :
