Fields containing complex data are not supported yet. If <EM>file</EM>.<EM>fea</EM> is "-", the standard input is read. By default, the output is in Unix GPS (``Graphics Primitive String'') format and is displayed on the graphics display, but with the <STRONG>-</STRONG> <STRONG>T</STRONG> option, this may be sent to the standard output, obtained in Tektronix format rather than GPS, or plotted on an Imagen laser printer. If the <STRONG>-r</STRONG> option is omitted, then the named <EM>field</EM> is plotted from the first record of <EM>file</EM>.<EM>fea</EM>. <EM>Plotfield</EM> finds the maximum and minimum values of the points to be plotted and computes appropriate scales for the <EM>x</EM>- and <EM>y</EM>-axes. These automatic values can be overriden by the <STRONG>-y</STRONG> or <STRONG>-Y</STRONG> options. The color and line style of output to ``gps'' or ``mcd'' depend on the environment variable BUNDLE. The default is GPS bundle number 20, which gives solid lines on monochrome displays. The fieldname to plot must be given with the <STRONG>-f</STRONG> flag. This is not optional and there is no default.</PRE><H2>OPTIONS</H2><PRE> The following options are supported: <STRONG>-r</STRONG> <EM>record</EM> <STRONG>-r</STRONG> <EM>first</EM>:<EM>last</EM> <STRONG>-r</STRONG> <EM>first</EM>:+<EM>incr</EM> Determines the records from which the named <EM>field</EM> is plotted. In the first form, a single integer identi- fies one record from which <EM>field</EM> is plotted. The <EM>x</EM> - axis shows element number within the field and the <EM>y</EM>- axis shows element value. In the second form, a pair of unsigned integers gives the first and last points of the range. If <EM>first</EM> is omitted, 1 is used. If <EM>last</EM> is omitted, the last record in <EM>file</EM>.<EM>fea</EM> is assumed. The third form is equivalent to the first with <EM>last</EM> = <EM>first</EM> + <EM>incr</EM>. When more than one record is plotted, the element values are catenated together before plotting with the <EM>x</EM> - axis showing the cumulative element number. (For example, if <EM>field</EM> has ten elements and two records are plotted, the <EM>x</EM>-axis will be labelled 1-20). <STRONG>-t</STRONG> <EM>text</EM> A line of text to be printed below the plot. By default, <EM>plotfield</EM> prints a line giving the fieldname, record number, and file name. An additional line may be printed via the <STRONG>-t</STRONG> option. <STRONG>-x</STRONG> <EM>debug</EM>_<EM>level</EM> If <EM>debug</EM>_<EM>level</EM> is nonzero, debugging information is written to the standard error output. Default is 0 (no debugging output). <STRONG>-y</STRONG> <EM>low</EM>:<EM>high</EM> Specifies approximate lower and upper limits for the <EM>y</EM>-axis. The values are adjusted by <EM>plotfield</EM> in an attempt to make an esthetically pleasing plot. See also the <STRONG>-Y</STRONG> option. If neither <STRONG>-y</STRONG> or <STRONG>-Y</STRONG> is specified, limits are calculated automatically. <STRONG>-T</STRONG> <EM>device</EM> <EM>Device</EM> may be <STRONG>gps</STRONG>, <STRONG>mcd</STRONG>, <STRONG>tek</STRONG>, or <STRONG>imagen</STRONG>. The default is <STRONG>-Tmcd,</STRONG> which displays the output on the graphics screen by piping it through <EM>mcd</EM>(1G). Specifying <STRONG>-</STRONG> <STRONG>Tgps</STRONG> sends output to the standard output in Masscomp Unix GPS for- mat. Specifying <STRONG>-Ttek</STRONG> causes output to be sent to the standard output in Tektronix 4000-series format, and <STRONG>-</STRONG> <STRONG>Timagen</STRONG> plots it on an Imagen laser printer in Tek- tronix 4014 emulation mode. <STRONG>-Y</STRONG> <EM>low</EM>:<EM>high</EM> Specifies exact lower and upper limits for the <EM>y</EM>-axis.</PRE><H2>EXAMPLES</H2><PRE> <STRONG>plotfield</STRONG> <STRONG>-f</STRONG> <STRONG>spec_param</STRONG> <STRONG>-r5</STRONG> speech.fana plots the <EM>spec</EM>_<EM>param</EM> field from record 5 of speech.fana. <STRONG>plotfield</STRONG> <<EM>options</EM>> <<EM>filename</EM>> is equivalent to <STRONG>plotfield</STRONG> <STRONG>-Tgps</STRONG> <<EM>options</EM>> <<EM>filename</EM>> <STRONG>|</STRONG> <STRONG>mcd</STRONG> The second form may be used if nondefault options for <EM>mcd</EM> are desired.</PRE><H2>ESPS PARAMETERS</H2><PRE> No ESPS parameter file is read.</PRE><H2>ESPS COMMON</H2><PRE> ESPS Common processing is disabled.</PRE><H2>DIAGNOSTICS</H2><PRE> <EM>Plotfield</EM> complains and exits if <EM>file</EM>.<EM>fea</EM> does not exist or is not a FEA file. It also exits if the nemaed field con- tains complex data.</PRE><H2>IMPLEMENTATION NOTE</H2><PRE> The current version of <EM>fieldplot</EM> is implemented as a shell script that pipes the output of <STRONG><A HREF="../man1.html/pplain.1.html">pplain (1-ESPS)</A></STRONG> through <STRONG><A HREF="../man1.html/testsd.1.html">testsd (1-ESPS)</A></STRONG> and <STRONG><A HREF="../man1.html/plotsd.1.html">plotsd (1-ESPS)</A></STRONG>. This is an example of how ESPS programs can be combined with the "Unix tools approach" - see the simplified example on the <EM>pplain</EM> (1 - ESPS) man page.</PRE><H2>EXPECTED CHANGES</H2><PRE> Many more options may be added.</PRE><H2>SEE ALSO</H2><PRE> <STRONG><A HREF="../man1.html/plotsd.1.html">plotsd(1-ESPS)</A></STRONG> <STRONG><A HREF="../man1.html/plotspec.1.html">plotspec(1-ESPS)</A></STRONG>, <STRONG><A HREF="../man1.html/mlplot.1.html">mlplot(1-ESPS)</A></STRONG>, <STRONG><A HREF="../man1.html/genplot.1.html">genplot(1-ESPS)</A></STRONG></PRE><H2>AUTHOR</H2><PRE> Manual page by John Shore Program by Alan Parker</PRE></BODY></HTML>⌨️ 快捷键说明
