Re: [Maxima-discuss] plot2d: how to plot multiple lines with the same style and color

[Jaime V. <vi...@fe...>]

plot2d ([sin(x), sin(2*x), sin(3*x)], [x, 0, 10], [style,[lines,1,2]]);

Will plot the three curves with the same style, namely, lines of width 
equal to 1, and a color code 2 which stands for red. Very confusing, I 
know; it is a remnant from old versions of Gnuplot when it was harder to 
set the linetype that would work in all gnuplot terminals. Today I think 
I could do better.

Jaime
