It is case sensitive (commands and function names written in lowercase are not the same as those written in CAPS). All command names may be abbreviated as long as the abbreviation is not ambiguous. Any number of commands may appear on a line (with the exception that load or call must be the final command), separated by semicolons (;). Strings are indicated with quotes. They may be either single or double quotation marks, e.g., £O؟ ·T v€ں€€‚€€‚€€‚‚م'hlI‰‚‚مéذع‰مd›lI‰مéذع‰مéذع‰‚ے load "filename" cd 'dir'although there are some subtle differences (see syntax for more details). Any command-line arguments are assumed to be names of files containing gnuplot commands, with the exception of standard X11 arguments, which are processed first. Each file is loaded with the load command, in the order specified. gnuplot exits after the last file is processed. When no load files are named, gnuplot enters into an interactive mode. The special filename "-" is used to denote standard input. See "help batch/interactive" for more details. …R HC3 4€¥€€‚مéذع‰‚‚€€‚ےMany gnuplot comma·HC‚ nds have multiple options. These options must appear in the proper order, although unwanted ones may be omitted in most cases. Thus if the entire command is "command a b c", then "command a c" will probably work, but "command c a" will fail. Commands may extend over several input lines by ending each line but the last with a backslash (\). The backslash must be the _last_ character on each line. The effect is as if the backslash and newline were not there. That is, no white space is implied, nor is a comment terminated. Therefore, commenting out a continued line comments out the entire command (see comment). But note that if an error occurs somewhere on a multi-line command, the parser may not be able to locate precisely where the error is and in that case will not necessarily point to the correct line. ش·SE7 <€©€€‚مéذع‰م¶ڑlI‰€€‚ےIn this document, curly braces ({}) denote optional arguments and a vertical bar (|) separates mutually exclusive choices. gnuplot keywords or help topics are indicated by backquotes or boldface (where available). Angle brackets (<>) are used to mark replaceable tokens. In many cases, a default value of the token will be taken for optional arguments if the token is omitted, but these cases are not always denoted with braces around the angle brackets. ;ًHCژFK d€ل€€‚م¶ڑlI‰م¶ڑlI‰€€‚‚مéذع‰مœalI‰€€‚ےFor on-line help on any topic, type help followed by the name of the topic or just help or ? to get a menu of available topics. The new gnuplot user should begin by reading about plotting (if on-line, type help plotting). CSEرF1ï?‰ےےےےرF NSeeking-assistanceK ژFIB R€€€€‚‚€مéذع‰‚€€‚‚€€‚‚ےSeeking-assistanceThere is a mailing list for gnuplot users. Note, however, that the newsgroup comp.graphics.apps.gnuplotis identical to the mailing list (they both carry the same set of messages). We prefer that you read the messages through the newsgroup rather than subscribing to the mailing list. Administrative requests should be sent to majordomo@dartmouth.eduSend a message with the body (not the subject) consisting of the single word "help" (without the quotes) for more details. ¯fرFثKI `€ح€€‚‚€€‚‚‚€€‚‚‚€€‚‚‚€€‚‚‚ےThe address for mailing to list members is: info-gnuplot@dartmouth.eduBug reports and code contributions should be mailed to: bug-gnuplot@dartmouth.eduThe list of those interested in beta-test versions is: info-gnuplot-beta@dartmouth.eduThere is also a World Wide Web page with up-to-date information, including known bugs: http://www.cs.dartmouth.edu/gnuplot_info.htmlBefore seeking help, please check the FAQ (Frequently Asked Questions) list. If you do not have a copy of the FAQ, you may request a copy by email from the Majordomo address above, ftp a copy from BI N6 :€€€€‚مéذع‰‚‚مéذع‰‚ے ftp://ftp.dartmouth.edu/pub/gnuplotor see the WWW gnuplot page. When posting a question, please include full details of the version of gnuplot, the machine, and operating system you are using. A _small_ script demonstrating the problem may be useful. Function plots are preferable to datafile plots. If email-ing to info-gnuplot, please state whether or not you are subscribed to the list, so that users who use news will know to email a reply to you. There is a form for such postings on the WWW site.

This section gives a partial list and links to the new items in no particular order. 1. fit f(x) 'file' via uses the Marquardt-Levenberg method to fit data. (This is only slightly different from the gnufit patch available for 3.5.) 2. Greatly expanded WN³€ Nusing command. See plot using. 3. set timefmt allows for the use of dates as input and output for time series plots. See Time/Date data and timedat.dem. 1àWNن‚Q p€ء€€‚‚‚م"pI‰‚‚م$pI‰م$pI‰‚‚مل pI‰‚‚مu³rI‰€€‚ے4. Multiline labels and font selection in some drivers. 5. Minor (unlabeled) tics. See set mxtics. 6. key options for moving the key box in the page (and even outside of the plot), putting a title on it and a box around it, and more. See set key. 7. Multiplots on a single logical page with set multiplot. 8. Enhanced postscript driver with super/subscripts and font changes. (This was a separate driver (enhpost) that was available as a patch for 3.5.) )ؤ³€ …e ک€‰€€‚م}طmI‰‚‚€€€€مِ¥mI‰‚‚مـءû‰‚‚م½=pI‰‚‚م‎
