.SH PARAMETERS
.TP 13
strings
: n vector of strings, strings(i) is the legend of the ith curve
.TP
style :
integer row vector of size n (the plot styles, third parameter
of plot2d) or an integer 2 x n matrix, style(1,k) contains the plot
style for the kth curve and style(2,k) contains the line style (if
style(1,k)>0) or mark color (if style(1,k)<0).

t=0:0.1:2*%pi;
plot2d(t,[cos(t'),cos(2*t'),cos(3*t')],[-1,2 3]);

xset("line style",2);plot2d(t,cos(t),style=5);
xset("line style",4);plot2d(t,sin(t),style=3);
