Ah.
Yes, that's exactly what I have.
The only difference is that I only have the board, plastic paper, and the pencil and wheel.

Thanks Nicole.

It has holes along each side so that you can put the ruler that comes with it in the holes and keep it from sliding around when you are trying to draw a straight line. My complete kit is actually a hoj poj of actual drawing kits and odds and ends that I have picked up over the years. The original kit consisted of the board, it's ruler, a right angle, one of those fabric wheels, and a kind of pencil looking thing for punching holes with one end bigger than the other. Usually, if I am trying to draw a line on a graph, I will use the small end of the pencil thing to punch holes through to the back of the paper. I will then flip the paper over and connect the dots (no pun intended) with the fabric wheel, using the ruler to make a straight line. The one thing about which one has to be careful is pressing too hard and cutting the paper. On the flip side of that, it does work well if you need to cut a straight line, and, like me, you are one of those people who could not cut a straight line with scissors to save your life. Anyway, the next part of the kit that I acquired was two separate parts. I received one of those tools that is supposed to pull up a dot when you press it into the paper and then pull up. It came with a rubber mat. However, it did not work very well, and I have since set it aside, but I still use the mat. I also received three more drawing tools, which were a double ended drawing wheel with a small end and an end that made two parallel lines, a double ended wheel that had a small end and an end with a wheel with larger spokes that were more spaced out, and another double ended pencil thing, which had a ball like point at one end and a more pointed part on the other end. Besides that, I have collected a number of other things. I have a rubber cord like thing that can be curved into different shapes; it is good for drawing parabolas. I have a piece of textured cardboard that I sometimes use instead of a drawing screen. I have a circle that I cut. Oh, and, I almost forgot, I also have a compass, but I don't like it much. You have to make the circle by punching individual holes. I would be interested to know if anyone has found one that works better. I also have two rulers that are attached together that you can separate or push together; they work well for drawing parallel lines. I also have fun tack for holding down the right angle or other things that I am trying to trace and sticky note tape. The board also came with some plastic paper that, when you drew on it with a pen or one of the pencil things, it raised up on the top instead of the other side, so you did not have to draw backwards. When I ran out of this, I found that the plastic from the printer paper packages worked fine as well. I might have more tools, but, as I am home for Thanksgiving and my drawing kit is back in my dorm room, I do not know what they are at the moment.

If it is not too complex, I use my tactile drawing kit, which can be purchased from several different places, including the Perkins Institute or APH. Sometimes, if there is a lot of data, I will use Excel. However, I only use Excel if I have a good understanding of what the graph looks like, as that is usually the point of drawing the graph. I used to have the AGC, but I don't have it anymore. With that, you can get a sound representation of your graph, which you cannot get with Excel.
