Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
-- Plot option: color [color, <color_1>, ..., <color_n>] In plot2d and implicit_plot, it defines the color (or colors) for the various curves. In plot3d, it defines the colors used for the mesh lines of the surfaces, when no palette is being used; one side of the surface will have color <color_1> and the other <color_2> (or the same color if there is only one color).
If there are more curves or surfaces than colors, the colors will be repeated in sequence. When using gnuplot, the colors could be: blue, red, green, magenta, black, cyan or black; in xmaxima the colors can be those or a string starting with the character # and followed by six hexadecimal digits: two for the red component, two for green component and two for the blue component. If given the name of an unknown color, black will be used instead.
