Graham is still searching for his first goal in City colours since joining on a season-long loan from Sunderland.
"There's been a lot of talk about him (not scoring) but I've been really pleased with the way he's helped the team. His link-up play and attitude has been first class," Bruce told the Hull Daily Mail.
"Not scoring doesn't concern me too much. For his sake I hope he gets off the mark because his performances certainly deserve it. He and Sone Aluko have done very well together so people will have to be patient. That includes Gedo and it includes (Yannick) Sagbo.
"He's got to stay strong with it. Every time he doesn't score it's going to get regurgitated week in and week out, but I'm not really interested.
"I've been delighted with his attitude and I hope he can get off the mark because he's a very good player. I've been watching him in training and he's a fantastic finisher.
"All strikers go through these droughts but it's a time when he needs his manager's support. He's certainly got that."
