Question

我使用gramm绘制一些数据。 长话短说：我想根据用户输入构建一个字符串，然后将其作为调用gramm函数的命令运行。

我的结构包含许多样本的数据 - 每个样本中的数据包含许多化学物种的强度。

我构建了一个条形图，显示了每个样品的每种化学物质的强度。换句话说，我的y轴是强度，我的x轴是化学物种，我的颜色是＆＃39;是样本。

现在我不想绘制每个样品甚至每个样品中的每种化学物质。就目前而言，我必须经历并对其进行硬编码。但是我想知道我想要绘制哪种化学物质和哪些样品。

截至目前，这意味着要写一个非常长的命令：

g=gramm('y', allData.(fileName).intensities, 'x', ...
    allData.(fileName).chemicalSpecies, 'color', ...
    allData.(fileName).sampleName,'subset',...
    allData.(fileName).sampleNum <u & ...
    allData.(fileName).sampleNum >l & ...
    allData.(fileName).chemicalSpecies =="Butanal" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Butenal" |...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Pentanal" |...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Pentenal" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Hexanal" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Hexenal" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Heptanal" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Heptenal"| ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Octanal" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Octenal" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Nonanal"  | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Nonenal" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Butanedial"| ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Pentanedial"| ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Hexanedial"| ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Heptanedial"| ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Octanedial" | ...
    allData.(fileName).sampleNum <u & allData.(fileName).sampleNum >l ...
    & allData.(fileName).chemicalSpecies == "Nonanedial")

正如您所看到的，此代码仅绘制了某个样本子集（在samplenum u和l之间）并且仅绘制了某些化学物种。

我喜欢的是输入我感兴趣的特定样本和化学物种，并使用该输入生成一行调用gramm函数的代码 - 无需对其进行硬编码如上所示。

基本上，我需要根据输入构造一个字符串，然后将该字符串作为调用gramm的命令运行。

谢谢！

编辑：澄清

我想要一个对话框出现的东西，并要求我选择我想要的样品和化学物质。让我们说我选择样品A，B，C和化学物质Propanal和Butanal。

目前，我必须自己硬编码：

g=gramm('y', allData.(fileName).intensities, 'x', ...
    allData.(fileName).chemicalSpecies, 'color', ...
    allData.(fileName).sampleName,'subset',...
    allData.(fileName).sampleName == 'A' &... 
    allData.(fileName).chemicalSpecies =="Propanal"
    allData.(fileName).chemicalSpecies =="Butanal" | ...
    allData.(fileName).sampleName == 'B' &... 
    allData.(fileName).chemicalSpecies =="Propanal"
    allData.(fileName).chemicalSpecies =="Butanal" | ...
    allData.(fileName).sampleName == 'C' &... 
    allData.(fileName).chemicalSpecies =="Propanal"
    allData.(fileName).chemicalSpecies =="Butanal")

我不想对此进行硬编码，而是希望创建一个包含所有这些内容的字符串，然后将其作为命令传递。

我认为这可以通过使用for循环来实现，该循环将字符串连接到每个sampleSame的数组。通过这种方法，我可以创建一个字符串：

constructPlot =＆＃34; g = gramm（＆＃39; y＆＃39;，allData。（fileName）.intensities，＆＃39; x＆＃39;，... allData。（fileName）.chemicalSpecies，＆＃39; color＆＃39;，... 。ALLDATA（文件名）.sampleName，＆＃39;子集＆＃39;，... allData。（fileName）.sampleName ==＆＃39; A＆＃39; ＆安培; ... allData。（fileName）.chemicalSpecies ==＆＃34; Propanal＆＃34; allData。（fileName）.chemicalSpecies ==＆＃34; Butanal＆＃34; | ... allData。（fileName）.sampleName ==＆＃39; B＆＃39; ＆安培; ... allData。（fileName）.chemicalSpecies ==＆＃34; Propanal＆＃34; allData。（fileName）.chemicalSpecies ==＆＃34; Butanal＆＃34; | ... allData。（fileName）.sampleName ==＆＃39; C＆＃39; ＆安培; ... allData。（fileName）.chemicalSpecies ==＆＃34; Propanal＆＃34; allData。（fileName）.chemicalSpecies ==＆＃34; Butanal＆＃34;）＆＃34;

当我输入constructPlot时，它会显示字符串，但我希望它作为命令而不是字符串运行。

您可以使用ismember组合条件：

names = [...
"Butanal"  
"Butenal" 
"Pentanal" 
"Pentenal"  
"Hexanal"  
"Hexenal"  
"Heptanal"  
"Heptenal" 
"Octanal"  
"Octenal"  
"Nonanal"   
"Nonenal"  
"Butanedial"
"Pentanedial"
"Hexanedial"
"Heptanedial"
"Octanedial" 
"Nonanedial"];
condition = allData.(fileName).sampleNum < u & ...
allData.(fileName).sampleNum > l & ...  
ismemeber(allData.(fileName).chemicalSpecies ,names);
