Plots the given data to screen using the supplied options.
Can either be a list or a nested list of a 1D or 2D array of y values or x-y points.
The options correspond directly to the options of the gnuplot 'plot' command.
Syntax note: wherever gnuplot expects a string as an option value, use a double-quoted ECLiPSe string - unquoted or single-quoted atoms will not work!.
% x-y pairs with 'points'
?- A=[1-3,5-2,9-2,8-2,5-7], plot(A, [with:points]).
% y values with large 'smooth' lines and points
?- A=[1,2,3,4,8,9,4,2,4,6], plot(A, [smooth: csplines,
with:linespoints,
pointsize:3]).
% multiple y values in nested lists with lines, boxes and titles
?- A=[[1,2,4,9,18,27,3],[1,4,16,36,25,16,9]],
plot(A, [with:[lines, boxes], title:['data 1', 'data 2']]).
% multiple y values in an array, in a certain range, with impulses of
% different widths
?- A=[]([](1,2,4,6,7,8,9),[](1,4,16,36,49,64,81)),
plot(A, [ranges:(3:6), with:impulses, linewidth:[8,2]]).
% multiple t-r pairs, in polar coordinates with a grid and lines
?- A=[[1-3,5-2,9-2,8-2,5-7], [1-2,5-4,8-6,9-1,12-4]],
plot(A,[set:[polar, grid=polar], with:lines]).
