The larger your organizational chart gets the more important it is to easily zoom in on the parts that are relevant.
Fast access view menu
By double-clicking on any blank part of the canvas around your org chart you can bring up a menu for all zoom controls.
You can now zoom in to 200% to give a closer look at the parts of your chart that are relevant. To zoom in either click the "+ Zoom in" icon or scroll up with your mouse wheel to zoom in on a particular location.
To zoom out you can either click the "- Zoom out" icon on the view menu or scroll down on your mouse wheel.
Step in for HIFI mode
When zoomed out in LOFI (low detail) view you can click on any position on the org chart to step into HIFI (high detail) view enough to make the details on the position visible such as position title and role.
Fit to view
To recenter and resize your view to fit your org chart you can either click the lens icon in the bottom right or double click on any blank part of your canvas and select fit to view.
