Common Commands in PlantUML

Discover the fundamental commands universally applicable across all diagram types in PlantUML. These commands allow you to inject versatility and personalized details into your diagrams. Below, we breakdown these common commands into three major categories:

Global Elements

  • Comments: Add remarks or explanatory notes in your diagram script to convey additional information or to leave reminders for further modifications.
  • Notes: Incorporate supplementary information directly onto your diagram to aid in understanding or to highlight important aspects.
  • Size Control: Adjust the dimensions of various elements to suit your preferences, ensuring a balanced and well-proportioned diagram.
  • Title and Captions: Define a fitting title and add captions to elucidate the context or to annotate specific parts of your diagram.

Creole Syntax Description

Harness the power of Creole syntax to further format the content of any element within your diagram. This wiki markup style allows for:

  • Text Formatting: Customize the appearance of your text with various styles and alignments.
  • Lists: Create ordered or unordered lists to present information neatly.
  • Links: Integrate hyperlinks to facilitate quick navigation to relevant resources.

Style Control Command

Gain complete control over the presentation style of your diagram elements using the style command. Utilize this to:
  • Define Styles: Set uniform styles for elements to maintain a cohesive visual theme.
  • Customize Colors: Choose specific colors for various elements to enhance visual appeal and to create distinct classifications.

Explore these commands to create diagrams that are both functional and aesthetically pleasing, tailoring each element to your exact specifications.

  • scale 1.5
  • scale 2/3
  • scale 200 width
  • scale 200 height
  • scale 200*100
  • scale max 300*200
  • scale max 1024 width
  • scale max 800 height
