Hughes had called for a reaction after their 4-0 thrashing by Everton on Saturday, and he was happy with the performance if not the result.
He said: "I felt we were the team who were in control of the game. I was pleased with that aspect of our play. It's important that we control the flow of the game and I know we did that.
"We needed something to drop for us in the box, that was what was missing. We had a number of half chances but none you could say was a real clear-cut chance that we could have converted.
"Apart from one attempt that Asmir had to deal with towards the end of the game, I didn't feel Cardiff caused us too many problems.
"The hardest part of football is converting chances and at the moment we're not quite able to do that most important thing."
