Changing the Arrow Type of a Connector - Microsoft Excel
In Microsoft Excel, to change the arrow style of a connector, right click on the connector and select "Format shape". From the left side menu, select "Fill & Line" (paint can) and select the desired arrow style from the drop-down menu next to "End Arrow Type". (In 2007, from the Format Shape menu select "Line Style" then select the desired arrow style from the drop-down menu for "End Type" under "Arrow Settings.")
