The chart shown in Figure 6-73 is a stock chart. As you see, for each product, a line is plotted to span a
range of values and has a large tick mark to indicate the position of a value within the high-low range.
In this example, the beginning (lowest point of the line) of the range is the standard cost of the product.
The tick mark represents the last receipt cost, and the high range of the line is the list price.
