Warnock, whose team were unlucky not to take all three points, insists he has made the right decision in giving Barton the armband previously worn by Adel Taarabt.
He said: "It was just a logical thing really. I had a chat with Adel last week. Adel was straight away right about it. He appreciates how far we have come now and that we need to drive on now.
"We need somebody as our leader. He (Barton) epitomised what we are about tonight. I thought he handled himself well.
"He just grabbed hold of us. We will have our moments where things won't go so well, but you have to have that in any healthy relationship."
