Assigning material resources is similar to assigning work resources with one exception: When you assign material resources, you specify the required quantity of material instead of the time the resource spends.
Figure 9-9. The overlapping lines for several resources quickly obscure the information you want. On the right side of the Graphs dialog box, you can turn off the checkbox to the left of the resource's name to temporarily remove that person from the graph. The table below the graph shows the values for all selected resources (whether or not they appear in the graph).
