Interacting with Charts

This documentation is an older version of JasperReports Server User Guide. View the latest documentation.

Once you have chosen rows and columns and selected the type of chart you want, you can further explore your data using interactive features such as brushing an area of the chart to zoom in or clicking on a legend to hide the members of a group.

Zooming

Zooming lets you view a specific area of a chart more closely. Zooming can also be helpful when the labels at the bottom of a chart are difficult to read, because only the labels corresponding to the selected area are displayed.

Zoom is a viewing feature of the Ad Hoc Editor. When you save an Ad Hoc view, or create a report from an Ad Hoc view, the zoom is automatically reset to show the whole chart.

To zoom in on an area of a chart:

•

Click and drag or brush the area you want to zoom in on. As you are dragging or brushing a pale blue area indicates your selection. When you release the mouse button, the view zooms in on the area you selected.

To view the whole chart again:

•

Click Reset zoom at the upper right of the canvas.

The following images show a bar chart before and after zooming:

Hiding Group Members

Use the legends below the chart to hide or show group members.

•

To hide a group member, click the member name in the legend below the chart. The member is removed from the chart and the legend is grayed out.

•

To unhide a group member that has been hidden, click the grayed-out legend for the member.

Hiding a Group Member

Hidden members are a view feature of the Ad Hoc Editor. When you save an Ad Hoc view, or create a report from an Ad Hoc view, the chart is automatically reset to show all members.
