All plot requests normally produce PLOT files in the default disk directory. Plot files are named PLOTmmnn.AC or PLOTmmnn.TR where the AC extension results from data generated during an .AC analysis and the TR extension results from data generated during a .TRansient analysis. The number 'mm' refers to the current circuit description and 'nn' is a plot sequence number within the current circuit analysis and any .ALTERations of the current circuit. The first analysis of a run generates plot files named PLOT00mm. The first plot file generated during the analysis is named PLOT0000. The second plot file is named PLOT0001, etc. The first plot file generated from a second circuit, defined after a .NEXT record, is named PLOT0100, etc.
Examples:
.PLOT AC 132 eout eout > 0.0 0.0 -180. 180.
.PLOT AC 132 eout 0. 0. eout > -180. 180.
Produces a 132 column ASCII plot of the AC data for the first part of eout and the second part of eout. The first part of eout will be automatically scaled by CCICAP. The second part of eout will be plotted between the limits of -180. (lower limit) and 180. (upper limit).
.PLOT AC PNG eout eout 0. 0. -.5 .5
Produces a PNG graphic plot of the AC data. The variable eout (first part) is plotted with both automatically scaled limits and user specified limits of -.5 to .5.
.PLOT AC PNG NDM INM ^19
Produces a PNG graphics plot file of the noise density measure, the integrated noise measure, and the 19th value in the output array from the current AC analysis with automatically scaled plot limits. The file will be named PLOTmmnn.AC.png where 'mm' will be the current .NEXT number for the run and 'nn' will be the number of the plot as produced by the current circuit. For example, if the above .PLOT request results in the 20th plot produced by the 3rd circuit in a run, the resulting plot file will be named PLOT0219.AC.
.PLOT TR 132 eout ^7
Produces a 132 column ASCII plot of the TRansient data. The variable eout and the seventh variable in the output structure are plotted with automatically scaled plot limits.
.PLOT AC PNG r45 iout
Produces a graphics plot file using the values of r45 for the independent variable values. The element r45 must have been specified on a .VARY .AC request in the current analysis. The output iout is used as the dependent variable and is plotted between automatically scaled limits.
.PLOT CLR
Clears all previous .PLOT requests and allows new plot requests to be stored. This can be used with an .ALTGO record as follows :
...
(end of .CKT section)
.END
.GO
.PLOT CLR
.PLOT ... (new requests)
