这个词就像 नोभेम्बर 是数据点，而数值是它们的向量表示。我想以这些表示为坐标并绘制它们以找到它们之间的关系。绘制它们的可能性是什么。非常感谢任何建议的工具。

Answer 1

我的 GUI 无法处理项目名称的字体，但如果我将它们命名为：a、b、cc、d、e，您可以使用平行坐标图来显示多维特征：

require(MASS)  # an R package
parcoord(data.frame(a=a,b=b,cc=cc,d=d,e=e), col=1:5)

Answer 2

这是一个 MATLAB 解决方案。

首先我们读取数据。尽管 MATLAB 能够读取 Unicode 文本，但它在 GUI 中显示它有一些问题（所以我只是用 Point1/Point2 等替换标签。）

%# read file lines
fid = fopen('data.txt', 'rt', 'native', 'UTF-8');
C = textscan(fid, '%s', 'Delimiter','\n');
fclose(fid);
C = C{1};

%# split into labels/data
labels = C(1:2:end);
data = cellfun(@str2num, C(2:2:end), 'UniformOutput',false);
data = cell2mat(data);

%# HACK: MATLAB has issues displaying unicode text
labels = num2str((1:size(data,1))', 'Point %d');

接下来我们可以使用平行坐标绘制数据：

%# you might need to normalize the attributes
%#data = zscore(data);

plot(data');            %'# plot lines
set(gca, 'XTick',1:numDim, 'XGrid','on')
xlabel('Features'), ylabel('Feature value')
title('Parallel Coordinates')
legend(labels)          %# show legend of labels

如果您有权访问统计工具箱，则可以使用多种技术可视化多元数据：

%# parallel coordinates (similar the above)
parallelcoords(data, 'Group',labels)

%# glyph plot (stars)
glyphplot(data, 'obslabels',labels, 'glyph','star')

%# glyph plot (Chernoff faces)
glyphplot(data, 'obslabels',labels, 'glyph','face')

%# Andrews curves
andrewsplot(data, 'Group',labels)
