The Summary Trends report is a graphical representation of project progress. Each project can be measured by examining the number of new issues being logged vs. the number of issues being closed, over time.
Use the dropdowns at the top of the page to select the project and the desired time period. Use the check boxes on the right to select what data to display.
"Opened Issues" and "Closed Issues" will show as bars on the dates that issues were created or closed. "Total Open Issues", "Total Closed Issues" and "Total Issues" will display as lines showing the trend over the selected period.
The Download... link can be used to download the raw numbers to a .CSV or .XLSX file for use in other applications.
