创建函数以灵活定义Mathematica中的图表选项列表 [英] Create Functions to flexibly define Chart Options lists in Mathematica

问题描述

我正在尝试创建一些功能，以避免我为不同类型的剧情重复剧情选项。当我尝试创建机制来自动处理Frameticks&绘制范围给定在给定绘图内考虑的数据。

pre $ 模块[{chartData}，
chartData = RandomInteger [20 ，20];

BarChart [chartData，
Frame - > {{True，True}，{True，True}}，
ImageSize - > 300，
ChartStyle - >黑色，
FrameLabel - > {{yName，None}，{None，xName}}，
ChartElementFunction - > FadingRectangle，
LabelStyle - >指令[Black，Bold，18]，
PlotRange - > {Automatic，1.3*Max@chartData}，
FrameTicks - > {{{Round @ Min @ chartData，Round @（Max @ chartData / 2），
Round @ Max @ chartData}，None}，
{{0，Round @（Length @ chartData / 2） ，Length @ chartData}，None}}
]]


现在，我试图简化我的生活：

  chartOptions [yName_，xName_]：= {Frame  - > {{True，True}，{True，True}}，
 ImageSize  - > 300，
 ChartStyle  - >蓝色，
 FrameLabel  - > {{yName，None}，{None，xName}}，
 ChartElementFunction  - > FadingRectangle，
 LabelStyle  - >指令[Black，Bold，18]，
 FrameTicks  - > {{{Round @ Min @ chartData，Round @（Max @ chartData / 2），
 Round @ Max @ chartData}，None}，
 {{0，Round @（Length @ chartData / 2） ，
 Length @ chartData}，None}}，
 PlotRange  - > {Automatic，1.3*Max@chartData}} 
  

这样，希望我的实际图表代码是这样的：

 模块[{chartData}，
 chartData = RandomInteger [20，20]; 
 
 BarChart [chartData，
 chartOptions [yName，xName]]] 
  

但这不起作用：

想法是，graphOptions函数将根据实际绘图的图表数据进行调整。

我现在试图只使用我真正理解的东西，所以我希望这样的问题不需要太多复杂的技巧:-)！
<解决方案问题是，在 chartOptions 变量 chartData 是一个引用全局定义的自由变量。在 BarChart 表达式中， chartData 变量被本地化为包含模块，因此对 chartOptions 。将 chartOptions 更改为接受 chartData 作为参数：

  chartOptions [chartData_，yName_，xName]：= ... 
  

然后相应地调整 BarChart 表达式：

  Module [{chartData }，chartData = RandomInteger [20,20]; 
 BarChart [chartData，chartOptions [chartData，yName，xName]]] 
  

I am trying to create some functions that will avoid me to repeat plot options for different types of plot. I encounter some troubles as I try to create mechanisms to automatically handle Frameticks & Plot Range given the data considered within a given plot.

Module[{chartData},
        chartData = RandomInteger[20, 20];

BarChart[chartData,
                Frame -> {{True, True}, {True, True}},
                ImageSize -> 300,
                ChartStyle -> Black,
                FrameLabel -> {{"yName", None}, {None, "xName"}},
                ChartElementFunction -> "FadingRectangle",
                LabelStyle -> Directive[Black, Bold, 18],
                PlotRange -> {Automatic, 1.3*Max@chartData},
                FrameTicks -> {{{Round@Min@chartData, Round@(Max@chartData/2), 
                                Round@Max@chartData}, None}, 
                              {{0, Round@(Length@chartData/2), Length@chartData}, None}}
          ]]

Now Here is my attempt to simplify my life :

chartOptions[yName_, xName_] := {Frame -> {{True, True}, {True, True}},      
                                ImageSize -> 300,
                                ChartStyle -> Blue,
                                FrameLabel -> {{yName, None}, {None, xName}},
                                ChartElementFunction -> "FadingRectangle",
                                LabelStyle -> Directive[Black, Bold, 18],
                                FrameTicks -> {{{Round@Min@chartData, Round@(Max@chartData/2), 
                                                 Round@Max@chartData}, None}, 
                                              {{0,Round@(Length@chartData/2),     
                                               Length@chartData}, None}},
                                PlotRange -> {Automatic, 1.3*Max@chartData}}

This so that hopefully my actual Chart code is as such :

 Module[{chartData},
         chartData = RandomInteger[20, 20];

         BarChart[chartData,
         chartOptions["yName", "xName"]]]

But this does not work :

The idea is that the chartOptions function will be adjusted given the chart data of the actual plot where it is used.

I am now trying to only use things I trully understand so I hope such a problem does not require to much of your sophisticated skills :-) !

解决方案

The problem is that in chartOptions the variable chartData is a free variable referring to a global definition. In the BarChart expression, the chartData variable is localized to the containing module and is thus invisible to chartOptions. Change chartOptions to accept chartData as a parameter:

chartOptions[chartData_, yName_, xName] := ...

and then adjust the BarChart expression accordingly:

Module[{chartData},chartData=RandomInteger[20,20];
  BarChart[chartData,chartOptions[chartData, "yName","xName"]]]
