Need Help With Reason

[Newbie dude]

So, I was making a drum track for a song, when all the sudden the little graph that I put the notes in manually just runs out, and theres nothing but white left. I can still put notes in, but I have no graph to keep rhythym. How do I fix this?

There is an E line on top of the graph. Just like there is an "R" line. All you have to do is drag this line over to gain more recording room.
