# Zoom Options

Enable report end-users to zoom the timeline easily by using **Button** or the **Wheel** options provided. It allows you to visualize the timeline at various levels of granularity.

To enable it: Go to the **Format Pane** -> **Chart Options** -> **Zoom Options.**

Set the Zoom options to either Button or Wheel for zooming.
