truenorth said:Funny you should ask. Emden Gansner and Dwight Perry implemented this feature in the current development snapshot, which in a few days should become the next stable release. It may require using a cairo back end (e.g. -Tpng:cairo).
Subscripts in DOT (GraphViz) are used to add text or symbols below or above a node or edge in a graph. They are commonly used to represent mathematical equations, chemical formulas, or other specialized notations.
To add a subscript in DOT (GraphViz), you can use the label attribute and enclose the subscript text in curly braces and preceded by the tilde symbol (~). For example, node1[label="~H2O~"]; will add the subscript "H2O" below the node named "node1".
Yes, you can use multiple subscripts in DOT (GraphViz) by separating them with a space. For example, node1[label="~H2O~ ~+~ ~CO2~"]; will add two subscripts, "H2O" and "CO2", below the node named "node1".
Yes, there are a few limitations when using subscripts in DOT (GraphViz). Subscripts cannot be used in conjunction with HTML-like labels, and they cannot be used in attributes other than label. Additionally, certain characters such as angle brackets, double quotes, and the tilde symbol itself, must be escaped with a backslash.
No, there is no built-in way to change the position or size of subscripts in DOT (GraphViz). However, you can use HTML-like labels to achieve this by using the port attribute and specifying the desired position and size for the subscript text. This method requires more advanced knowledge of the DOT (GraphViz) syntax.
