There are a number of actions you can take on each report. You can access some these by right-clicking the report name in the list of reports, which brings up the Report options context menu. Alternately, once you have run a report, there are buttons across the top of the view to invoke each of these:
Chart: Only present if the report is capable of displaying a chart. Clicking this option toggles between the report and the chart.
Configure report: Change the properties of this report. You can customize the report to your liking and save it for future use. See the next section for more details
New report: Create a new, customized report based on the selected report.
Export report: Reports can be exported, or saved, in HTML or CSV format. HTML is intended to preserve the displayed formatting of the report. CSV exports the data underlying the report.
Delete report: Customized reports can be deleted. The default reports that ship with KMyMoney cannot be deleted.
The Close report button was removed in 5.2. To close the current report tab, click the small x to the right of the report name on the tab.
