Drawing arrows

We already saw how to add basic arrow tips to lines and edges: we added the -> option to get a right arrow tip. However, the default arrow tips look a bit small and thin. Let’s see how to modify them.

The general syntax is \draw[starttip-endtip] or edge[start arrow-endarrow]. Previously, we had just > as the end tip and no start tip.

Quick examples are provided in the following list:

• ->: Right arrow, <-: Left arrow
• <->: Left and right arrow
• ->>: Double right arrow, <<-: Double left arrow
• -Triangle: Triangle-shaped arrow
• -Stealth: Stealth-plane-shaped arrow
• -LaTeX: Black triangle arrow with slightly bent sides, like \vec in LaTeX picture mode

You can combine one or several tops at an arrow’s start and end.

When you use arrows, always load the arrows.meta package:

\usetikzlibrary{arrows.meta}
