What does the 'w=' option in the SYMBOL statement control?

• A. Line color
• B. Symbol shape
• C. Line width
• D. Interpolation method

Answer: (C)

The 'w=' option in the SYMBOL statement specifically controls the line width in SAS graphic output. This option allows you to specify how thick or thin the lines will appear in your graphical representations. By setting this option, you can enhance clarity or aesthetics in your graphs, making certain lines stand out based on their width. While other options pertain to different aspects of graphical customization—such as line color, symbol shape, or interpolation methods—they do not define the line width. Understanding the role of the 'w=' option helps in effectively utilizing graph presentations to ensure that visual differences in line thickness can convey varying priorities or functionalities within the data being visualized.
