[sorry, has been asked before but forgot]: how do I plot 9 curves with automatic colour sequencing? o Problem #1: colour 8 is white and I cannot see my curve o Problem #2: colours >= 9 become rather non distinct Is there an easy solution without complex SciLab acrobatics? The same topic was dealt with on 202-03-20 @ https://www.mail-archive.com/users@lists.scilab.org/msg11103.html Defining a general strategy of automatic assignment of curves style is not necessarily trivial. The current strategy is not the same for plot(): cycling over 7 colors ; and for plot2d(): scanning the current colormap Whatever the strategy that you design and then propose and use, it will always have a limit. You can't expect to have a always valid method. The current plot() strategy could be improved for instance by cycling in a nested way first over line styles, starting with solid lines as now, and then over line colors. This would increase the limit to 7x10=70 styles, instead of currently 7. Please feel free to open a report about the topic if you deem it is worthwhile, with a rationale. Any actual algorithmic proposal is also welcome. There is no general solution, but there are easy ways to customize the curve styles by hand, even at calling time, without post-processing. x = 0:.05:1; clf reset plot(x, sin(x'*(1:10)), "color",[1:6 13 17 28 32]) // "color" option legend(msprintf("Curve #%d\n",(1:10)'), "in_lower_left"); [cid:part1.37Mim3rA.GDIR3PW8@free.fr] With plot2d(), you get the same figure without the legend with: x = 0:.05:1; clf reset plot2d(x, sin(x'*(1:10)), [1:6 13 17 28 32]) You may also customize the colormap before calling plot2d(), without the style option. The hsvcolormap is quite handy because it alternates colors: x = 0:.05:1; clf gcf().color_map = hsvcolormap(11); plot2d(x, sin(x'*(1:10))) legend(msprintf("Curve #%d\n",(1:10)'), "in_lower_left"); [cid:part2.pmU8pSci.HfJ9HZA4@free.fr] All these options are documented.
