My version is 9.0
I want to apply ColorData and Line Width styles at the same time, like the ColorTheme Function new in 10.0, but there is always errors. Codes under here:
a[x_] := Sin[x]
b[x_] := Sin[x - 2 Pi/3]
c[x_] := Sin[x - 4 Pi/3]
f[x_] := Max[a[x], b[x], c[x]]
g[x_] := Min[a[x], b[x], c[x]]
Plot[{f[x] - g[x], a[x] - b[x], a[x] - c[x], b[x] - c[x], b[x] - a[x],
c[x] - a[x], c[x] - b[x]}, {x, 0, 5 Pi},
PlotStyle -> {Thick, Dashed, Dashed, Dashed, Dashed, Dashed, Dashed},
PlotRange -> {-2, 2},
AxesLabel -> {\[Omega] t, Subscript[u, Subscript[VT, 1]]},
AxesStyle -> {{Arrowheads[{0, 0.025}], Italic, 12,
FontFamily -> "Helvetica"}, {Arrowheads[{0, 0.025}], Italic, 12,
FontFamily -> "Helvetica"}}]
And graph is
How can i make lines separately Dashed and Thick, and at the same time the graph can use ColorData for a different view?
