Hi.
I've created (after some effort), a function that plot into a Smith chart a
set of data.
In this function, all works OK, but I'd like to set default options for
MultipleListPlot in a different way.
My function in made in this way:
MultipleListSmith[lista_List,options___] :=
Module[{listaUV},
....I modify listaUV here...
MultipleListPlot[listaUV, options]
]
now, my data by default is created by four sets of xy data
{{data1},{data2},{data3},{data4}}, so I must to do four plots with
MultipleListPlot.
I't works all (now...), but I'd like to create, by default, four different
styles for every plot, in this way:
SymbolShape->None, PlotStyle->{{Red},{Blue},{Green},{Orange}},
PlotJoined->True
I'd like that these options are used by default, changing them when I need
other styles (considering that lista represents four data sets, by
default).
I've used the default value
options___:{PlotJoined -> True, SymbolShape -> None, PlotStyle -> {{Red},
{Blue}, {Green}, {Orange}}}
But it does not work, returning the plot with default options, not mine...
I've also tried the example shown in the mathematica book of the online
help 2.3.10, so, I've written:
Options[MultipleListSmith] = {PlotJoined -> True, SymbolShape -> None,
PlotStyle -> {{Red}, {Blue}, {Green}, {Orange}}};
MultipleListSmith[lista_List, options___]:=
Module[
.....
MultipleListPlot[
listaUV,
PlotStyle /. {options} /. Options[MultipleListSmith],
PlotJoined /. {options} /. Options[MultipleListSmith],
SymbolShape /. {options} /. Options[MultipleListSmith]
]
]
but it returns errors to me, of this type:
MultipleListPlot::badargs :
MultipleListPlot has been given bad arguments. Input Should be data sets
consisting of points or points with ErrorBar specifications.
If I replace my last three arguments with options, all works fine, but I
don't have dafault values that I wants...
Anyone can help me?
Thanks for your answers
Daniele
