The xgraph command will produce plots using the UNIX xgraph utility.
xgraph file plotargsThis command is similar to the plot command, however the xgraph program (an obsolete plotting package) actually generates the plots. If the given file is either ``tmp'' or ``temp'', then a temporary file is used to hold the data while being plotted. Polar and Smith plots are not supported, otherwise the variables associated with the plot command apply.
The xglinewidth variable specifies the line width in pixels to use in the plots. If not set, a minimum line width is used.
If xgmarkers is set, point plots will use cross marks, otherwise big pixels are used.
