The trend chart displays a visual representation of the magnitude of the selected metric over the selected time period. The horizontal axis represents the date, and the vertical axis represents the value of the metric selected for display. The green trend line plots the metric values that occurred during the selected time frame, until the day before the current date. As you move your mouse pointer over any point on the trend line, a balloon displays the actual magnitude of the selected metric on that date.
You can choose to display the metrics aggregated by day or by week, as well as the time frame to display. You can also select the check boxes below the chart to display vertical lines indicating the dates of changes in Teradata system version or ruleset.
