Please help me in plotting Roc curve with 5 Sn and 5 Sp values. i have plotted the graph but i am getting only one line out of 5 classes. i want to do a comparison with roc curve.i have TP values and i calculated FP=1-sensitivity.

Could you please provide the code?

Did you use "hold on" while printing?

TP=[45.01;67.01;85.2;67.33;98.9]

TP =

   45.0100
   67.0100
   85.2000
   67.3300
   98.9000

>> SP=[73.33;68.15;79.0;73.78;100]

SP =

   73.3300
   68.1500
   79.0000
   73.7800
  100.0000

>> FP=1-SP;

>> plotroc(TP,FP);
