Most of the examples in this book that invoke the %PLOTIT macro are created with a specific set of options. The graphics are generated by using a special macro variable called plotitop .
The code you see in the examples creates the color graphics that appear in the online (CD) version of the manual. A slightly different set of options and statements are used to create the black-and-white graphics that appear in the printed version of the book.
To create the online (color) version of the graphic output, the plotitop variable is defined as follows .
%let plotitop = gopts = gsfmode = replace gaccess = gsasfile device = gif hsize = 5.63 vsize = 3.5 cback = white, cframe = ligr, color = black, colors = red blue white, options = noclip expand, post=myplot.gif;
To create the black-and-white version of the graphic output, which appears in the printed version of the manual, the plotitop variable is defined as follows:
%let plotitop = gopts = gsfmode = replace gaccess = gsasfile device = pslepsf hsize = 5.63 vsize = 3.5 cback = white, color = black, colors = black, options = noclip border expand, post=myplot.ps;
