The concept behind the Stacked Trend chart is similar to that of the Pie chart, except that the values are plotted over time. One line of a different color is displayed per table row. Up to ten rows are plotted per chart. The lines are filled and stacked, with the highest table row plotted on the bottom of the chart. A downward fill below each line helps you see how each region of data is related to the others and to the larger metric.
A thick line labeled "Total" identifies where 100 percent of the plotted metric falls along the Y-axis. To remove this line from the chart, click the Hide link next to the legend.
This type of chart is most useful for comparing the relative contributions of selected entities to a performance metric over time. For example, filter on a particular server and select the Server/Client Pair view. A Stacked Trend chart for the TCP Bytes metric indicates whether data volumes from different clients are changing over time.
The Stacked Trend chart is not applicable for certain types of metrics, such as TCP Byte Loss Percentage.
