Label connectors
Connectors can have three labels - one in the middle, and at either end.
Double click on the connector at the location where you want to add a label. Alternatively, drag a Text shape from the Shapes panel and drop it onto a connector to add it as a label at that position.

Move a connector label
These labels will move with the connector as you move the shapes around on the drawing canvas, but you can also drag them to another location.
- To manually change a label's position, select the label by clicking on it, then drag the diamond grab handle to a new position

Rotate a connector label
Select the label on a connector, and use the rotate grab handle to rotate the text.
Tip: In some shapes, you can change the writing direction of the labels from horizontal to vertical.
Copy and paste a connector label
Select a label on a connector, copy it, then paste it. If the mouse pointer is on or near the connector when you paste, the new label is placed at that point on the connector. Otherwise it is pasted with a small offset so it does not cover the original label.
Edit a connector label
- Double click on the text to edit the label
Format and style the text
Use the Text tab in the format panel to change the style of a connector label.
You can add line breaks in connector labels, use a different font or font size or an external font, and add HTML formatting including superscript and subscript.
