I'm having trouble figuring out how to make a cumulative graph...I don't think there is a way but I will post it up in case anyone knows how.
What I am trying to do is for example, the person is given a target amount of 50 calls to be made for the week. Every day, they enter how many calls they made.
The graph would have zero on the bottom left corner, and 50 on the upper right corner of the graph. Then, every day, the amount accumulates either reaching the target, falling short, or going higher than it.
