Reports | Work item VA plot
This option allows you to print a chart - a Value-Added plot - showing the position of each student for a given work item (usually test or exam), as an (X,Y) point where X is the target (GCSE) score and Y is the mark obtained. On selection of the option, the same panel appears on the right as in Reports | work item Rank order so you can select the format of the labels (student names) on the points plotted. You can also select whether you want labels or not on the plot by checking or unchecking the "Labels on VA plots" checkbox.
Again, select the column to be plotted by clicking it, after choosing the label options.
