Dataplot Characters

Introduction Dataplot can draw a curve as a character or plot symbol at each point, as a connected line, as a spike from the point to a base, as a bar from the point to a base, or as any combination of the above (including drawing none or all of them). The choice is determined by the LINE, CHARACTER, SPIKE, and BAR commands. The switches for these commands work independently of each other.
Available Character Types The available character types are from 5 categories:
  1. common plotting characters
  2. any ascii keyboard character
  3. Greek symbols
  4. mathematics symbols
  5. miscellaneous symbols
  6. sample plot demonstrating use of characters
Case and Font The case (upper versus lower) and font (simplex, duplex, triplex, etc.) of the plot character follows the current setting of the CASE and FONT commands. The Greek, math, and miscellaneous symbols are available only when one of the Hershey fonts have been specified via the FONT or CHARACTER FONT commands.
