Pan and Zoom a Diagram

When you are viewing a diagram, you can pan across, up and down the whole diagram in a low magnification to locate a particular section, and then zoom into that section in a higher magnification.

Pan over diagram

You can pan over the Diagram View using the:

• Left, Right, Up, Down, Page Up, Page Down, Home and End keys when the Diagram View is selected
• Diagram scrollbars
• Middle mouse button
• Pan & Zoom window (Ctrl+Shift+N)

Zoom into and out of diagram

You can zoom into and out from the diagram using the:

• 'Diagram | Zoom' menu options or
• Zoom buttons on the Diagram toolbar or Pan & Zoom window toolbar
  
  

Change the zoom level by clicking on either the Zoom In (+) button or Zoom Out (-) button; each click changes the magnification by 10%. Alternatively, select the 'Zoom In' or 'Zoom Out' options from the 'Diagram | Zoom' menu.

You can return the diagram to 100% in one of three ways:

• Click on the ('Zoom to 100%') button
• Select the 'Diagram | Zoom | Zoom to 100%' menu option
• Press Ctrl and click on the middle button of the mouse

Notes

• You can zoom in and out of the main window dynamically by holding Ctrl and rolling the mouse wheel
• Changes in diagram magnification through the zoom options can be saved as permanent changes to the diagram
• At high levels of zoom, element features cease to display; this is because the Windows font mapper cannot easily select a font for extreme conditions, and the result can look odd
