ROC curve from an array of Confusion Matrices (true positive rate and false positive rate)

It should work in the first figure if the two values are paired!

Of note, I use the terms SEN and 1-SEN, so I didn't look up the def for hit rate.

What exactly is your goal? A ROC curve is created from a single experiment. There probably is some meta analysis equivalent but you don't typically take independent experiments with pre selected cutoffs and create a ROC curve from that.

And you definitely don't independently sort the columns like you did in your second image.

I think you need to better describe your data in order for us to help. How do you get a SEN and SPEC out of a single observation subject, etc.?
