A column chart presents values as vertical bars. For example, the standard report Effort by organization unit (pyEffortProgressByOrgUnit) in the Monitor Processes standard report category in the Report Browser shows, for each organizational unit, the effort in days to date for unresolved work items.
Column charts can be of several different chart types.
You can use a column chart to display the data in a Report Definition report by selecting the chart type in the toolbar at the top of the Chart Editor.
