15.5.429.1 Plot and Line Styles

The arguments to symbol and line must be integers between -9 and 29, inclusive.

The symbol and line styles are as follows. Styles 1 through 9 refer to symbols at the locations of the data points, connected by lines. The symbols are:

1. dots (.)
2. plus (+)
3. times (x)
4. box
5. upward-pointing triangle
6. diamond
7. downward-pointing triangle
8. four-line asterisk (+ and x combined)
9. circle

Styles -9 to -1 refer to symbols at the locations of the data points, without connecting lines. The symbols are the same as for the corresponding positive numbers. Style 0 is invisible. Styles 10 through 19 refer to variously dotted and dashed lines connecting the data points. The styles are:

10. short-dashed
11. medium-dashed
12. long-dashed
13. dot-short-dashed
14. dot-medium-dashed
15. dotted
16. dot-dot-dashed
17. dot-dash-dashed
18. dot-dot-dash-dashed
19. short-medium-dashed

Style 20 refers to a bar-style plot in which successive data points are connected by a horizontal and a vertical line. Styles 21 through 29 refer again to symbols at the locations of the data points, connected by lines. The symbols are:

21. e
22. f
23. g
24. h
25. i
26. j
27. k
28. l
29. m

You can use line to select the line style connecting the symbols selected with a positive symbol. By default, the symbols are connected by solid lines.
