Hi,
that is no wonder, because
PlotStyle /. {options} /.
Options[MultipleListSmith]
will evaluate to
{{Red},{Blue},{Green},{Orange}}
and not to an option for MultipleListPlot of the
form:
PlotStyle -> {{Red},{Blue},{Green},{Orange}}
You have to write
PlotStyle->(PlotStyle /. {options} /.
Options[MultipleListSmith])
or better
{mystyle,myjoin,myshape}={PlotStyle,PlotJoined,SymbolShape}
/. {options} /. Options[MultipleListSmith];
MultipleListPlot[
listaUV,
PlotStyle -> mystyle,
PlotJoined -> myjoin,
SymbolShape ->myshape
]

| 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
