The 27-year-old has not started for the Swans since an early October draw with Reading, though injury prevented him being involved in last weekend's meeting with Southampton.
But Graham, who scored 14 goals in 39 games last season, believes the decision to omit him from the first team was a correct one.

"I was in the team 99 per cent of last year, but the gaffer's come in and over the past few games I feel as though my performance hasn't been so good. "
The forward also insisted every footballer must deal with not being selected at some point in their career but underlined the importance of remaining calm.
Graham continued: "Just because I was dropped for two or three games doesn't mean I'm going to spit the dummy out and go knocking on the door and say I should be playing or I want to leave.
"You know as a professional footballer you're going to get dropped one or two times in your career.
"It's how you deal with it that counts. I feel I've dealt with it well. “
The former Watford frontman went on to reveal that he is pleased with his efforts in training ahead of the upcoming clash with Newcastle.
He added: "I've trained ever so well, I've trained ever so hard. I played in the under 21s game the other night just to get 90 minutes to make sure I'm ready.
"It's just a case of getting my head down in training and showing the gaffer that I'm ready to play and ready for selection whenever called upon.
"It's been a test, you know, but it's been a good one.”
