Note that the graph reflects the filters you apply advanced filters, certain grid filters, and the number of rows you select to display in the grid. For example, if you choose filter the Min Borrowed column to show only 20 rows of data in the grid, only those values greater than 1 and limit the number of rows displayed to 20, the graph results will also be limited to Min Borrowed values greater than 1 and the 20 rows of data will be depicted in the graph.
