Hello there, i recently implemented a Bag of Words categorization algorithm based on the one described in this paper

All works well, but i'd like to measure accuracies of the classifiers using ROC curves or, perhaps, precision-recall graphs.

I can easily get the confusion matrix for each of the classifiers but i don't know what parameter i should change to get more points and actually plot the curves.

Could someone please explain this to me?
