# Limited styles in the Monochrome plot theme

It seems like PlotTheme -> "Monochrome" produces up to 8 different dashing styles for Plot. I know one way to overcome this is to use ListLinePlot and use PlotMarkers to produce more combinations. However, I am wondering if there are simpler ways to just assign more dashing styles in the Monochrome theme? For example, as seen below, the styles repeat themselves.

Plot[Evaluate@Table[2 p + y, {p, 0, 1, 0.1}], {y, 0, 4},
PlotTheme -> "Monochrome"]


• It's more than you get with the normal plot theme, there the colors start repeating after p=5 Commented Feb 22, 2017 at 21:33
• A humble recommendation to the poser: Ask the minimally informative question. There's no need to complicate your question by using functions requiring Exclusions, or large number of PlotPoints, or to choose the size and FontFamily, etc. to learn what you seek. Plot[Evaluate@Table[a x^2, {a, 1, 2, .1}], {x, 0, 1}, PlotTheme -> "Monochrome"] suffices. Commented Feb 22, 2017 at 21:47
• @DavidG.Stork good point. I'll change it. Commented Feb 22, 2017 at 21:51
• @JasonB. They repeat after 5? Which ones? Commented Feb 22, 2017 at 21:59
• @rcollyer - they repeat after 5 if you squint..... that blue followed by a yellow looks similar to the first blue followed by a yellow. But yeah, I was clearly wrong Commented Feb 22, 2017 at 22:05

One solution would be to double the number of plot styles under this theme by making them gray. So you would have 8 black styles, followed by 8 gray styes.

Learning from the answers here, you could do this via

SystemPlotThemeDumpresolvePlotTheme["Monochrome", "Plot"] =
ReplaceAll[
SystemPlotThemeDumpresolvePlotTheme["Monochrome", "Plot"],
HoldPattern[Rule["DefaultDashing", dashing_List]] :>


Now you can have up to 16 distinct styles,

f[x_] := x^4 + x
g[x_] := x^2
tSet = Table[f[x] + c*g[x], {c, -4, 8}];
Plot[Evaluate@tSet, {x, -2, 2}, PlotTheme -> "Monochrome",
PlotLegends -> "Expressions"]


PlotStyle -> (Dashing[#]& /@ Table[i, {i, .01, .09, .01}])


or whatever style you like:

{Dashing[{.02, .05, .01}],Dashing[.04], Dashing[{.01, .02, .01, .06}],...}


or of course AbsoluteDashing

• This works but loses the first seven wonderful default styles of the Monochrome theme. Can it be done somehow to be used after the default styles have been exhausted? Commented Feb 22, 2017 at 21:58
• You're making this harder than it need be. Blow up a plot and then by hand enter the dashing values for the five styles (matching the rendered lines), and then you're done. You'll save so much time if you do this. [Over and out.] Commented Feb 22, 2017 at 22:16
• I can adopt your suggestion by using AbsoluteDashing[{d1, d2, d3,..}] that has the ability to produce all different dashing styles that I want. Thanks! Commented Feb 22, 2017 at 22:28
