How can i Plot ROC for more than 1 classifier?

Hi every body:

I'd like to ask if i have classifiers result as follow and i want to represent it on ROC, what can i do??

Class TP FP

ANN 32 8

SVM1 38 2

SVM2 30 10

KNN 35 5

I am trying to use that relation but i don't know how to place my data?

[X,Y,T,AUC] = perfcurve(labels,scores,posclass)

Can anybody please help me through that issue... Thanks a lot

Use separate axes, or if you want the curves all on one axes, then call hold on after you plot the first one.
