What's the best way to set a quota line on a graph? There are two methods. To set a graph where the line is set from a specific date to a specific date (such as the 3rd quarter), see the article here: How to set the line on a quota graph for a fixed time
The simplest way to set the quota so the graph will look correct both when you look at it "accumulating" and "regular" is to break down the total for the time period into each portion you'll be entering. For example, if you're working with a stat that has an annual quota of 4800, enter 400 per month in the quota box. When you view the graph, make sure to check the "Accumulating" box.
