how to plot percentage accuracy graph?

i want to use radial basis function for breast cancer detection.here is the code:

load breast_data inputs=data; targets=label; net=nwerb(inputs,targets,0.01,1.0); outputs=sim(net,inputs); [c,cm,ind,per]=confusion(targets,outputs); disp(cm);

but confusion matrix is no giving the correct output. also i want to plot percentage accuracy=(correct result/all results)*100 can any one help me. thanks
