Trend reports show how the value of one or more items changes
over time. Values along the horizontal axis of the trend report represent the time measurement.
Values on the vertical axis represent the changes to the items being monitored.
Users with the report_admin role can define the ranges that are used in a trend chart report.
See Report ranges for information on creating report ranges.
An example of an item that changes over time is incident count. The incident count will likely
increase during the first few months after a product upgrade is released. Over time, the number
of incidents reported drops as users become more accustomed to the changes in the product.
