1.2.5-19 Depicting Bands in Segmented Curve Graphs

All segments in a segmented curve graph should be related to the total value.

Additional Information:
A segmented curve graph contains a series of bands depicting the components of a total series (see Figure 1.7). The values of the bands, segments, or strata are plotted on an X-Y plot. The bands are added to one another so that the topmost boundary represents the sum of all bands. For example, segmented curve graphs can be used to show how much each pump is contributing to total flow. This format is most useful when all elements contribute equally to the total under normal circumstances. Segmented curve graphs should not be used when changes in the movement of a series are abrupt, or where accurate reading of a component is of paramount importance.
