22 ## Decode plot option strings. |
|
|
23 ## |
|
|
24 ## If OPT is a valid option string, return a string of the form "w l 2" |
|
|
25 ## ("with lines 2"). Uses abbreviations for the options to avoid |
|
|
26 ## overrunning gnuplot's command line buffer unnecessarily. |
|
|
27 ## |
|
|
28 ## OPT can currently be some combination of the following: |
|
|
29 ## |
|
|
30 ## "-" for lines plot style (default). |
|
|
31 ## "." for dots plot style. |
|
|
32 ## "@" for points plot style. |
|
|
33 ## "-@" for linespoints plot style. |
|
|
34 ## "^" for impulses plot style. |
|
|
35 ## "L" for steps plot style. |
|
|
36 ## "#" for boxes plot style. |
|
|
37 ## "~" for errorbars plot style. |
|
|
38 ## "#~" for boxerrorbars plot style. |
|
|
39 ## "n" with n in 1-6 (wraps at 8), plot color |
|
2697
|
40 ## "nm" with m in 1-6 (wraps at 6), point style (only valid for "@" or "-@") |
|
2311
|
41 ## "c" where c is one of ["r", "g", "b", "m", "c", "w"] colors. |
|
3062
|
42 ## ";title;" where "title" is the label for the key. |
|

|
43 ## |
|
|
44 ## Special points formats: |
|
|
45 ## |
|
3062
|
46 ## "+", "*", "o", "x" will display points in that style for term x11. |
|
