To add or change an arrowhead on a line, select the line in your workspace, then choose Arrowheads from the Line Style drop down menu on the Home tab. Select desired arrowhead from the drop down menu, or choose Custom to create a custom arrowhead.
Note: When changing the arrows on Automatic Shape Connectors, like those used in organizational charts and cause and effect diagrams, the entire chain or branch will change with your selection.
If you click on Custom and you'll be able to:
- Set the size of your arrow
- Choose its displacement (whether it touches the shape or not)
- Make it so that the style of arrow on both sides of the line is different (useful for technical diagrams)
- Choose a unique arrow style
