Dear Mathematica Users, I have a question about the coloring and dashing lines in listplot. For example, Let's say there is a multiple data set like data = Table[RandomReal[{2 i, 2 i + 1}, {20}], {i, 9}]; I want to plot them in listplot or listloglogplot with all different color and all different dashing with (joined -> True). How can I do it automatically or minimum option? The default number of coloring in mathematica (I am in still 8) is 4. after that, it repeat same color. please help me! Thanks! There are several such possibilities to make different colors. The most straightforward is as follows: data = Table[RandomReal[{2 i, 2 i + 1}, {20}], {i, 9}]; ListPlot[data, Joined -> True, PlotStyle -> Table[Hue[i/9], {i, 1, 9}]] Try it. You may use the RGBColor as well: ListPlot[data, Joined -> True, PlotStyle -> Table[RGBColor[i/9, 0, 1 - i/9] , {i, 1, 9}]] try various combinations of colour variation: RGBColor[i/9, 0, 1], RGBColor[0, 0, 1 - i/9], RGBColor[0, i/9, 1 - i/9] and so on. Try it. You may as well use a ColorData: ListPlot[data, Joined -> True, PlotStyle -> Table[ColorData[3, "ColorList"][i/9], {i, 1, 9}]] and look, e.g. into ColorData with different numbers. However, if it is something I really care how it looks like, I do it "by hand": ListPlot[data, Joined -> True, PlotStyle -> {Red, Blue, Green, Brown, Pink,Cyan, Magenta, Gray, Orange}] You have also possibility of using Darker[ ] function: ListPlot[data, Joined -> True, PlotStyle -> {Red, Darker[Red, 0.5], Blue, Darker[Blue, 0.5], Green, Darker[Green, 0.5], Pink, Darker[Pink, 0.5], Cyan}] Try it.
