Zooming on a chart

There are many ways to change the zoom level on a chart. You can use options in the Command Bar and Settings dialog, as well as mouse action and keystroke combinations.

Command bar options

Two zooming commands are available in the Command Bar:

Home Zoom
Selected by default, zooms to the X-axis of the primary data set. If you change the zoom level, you can click the HomeZoom button in the Command Bar to revert to the original zoom level.
NOTE: If the primary data set is numeric, the default zoom level focuses on the Y-axis.
Time Zoom
Zooms on the X-axis to show the time period specified in the Time Range dropdown menu.

Settings option — Data Zoom Scope
