Typographic Units

A number of options take a typographic unit as an argument. These options are marked with the type <measure>.

The following typographic units are currently accepted. Users are encouraged to specify typographic measurements using the "em" or "pt" units. Doing so will allow you to scale the output resolution of the chart using the global dpi option.

• px – Pixels
• mm – Millimeters
• pt – Typographic points
• em – Typographic "em" size
• % – Relative to the enclosing element

Examples

;; 40mm

;; 16 points
16pt

;; 2 "em"

;; 50% of the parent
