科學(xué)論文的寫作少不了用圖表對(duì)重要數(shù)據(jù)進(jìn)行展示，以圖表形式展示材料屬性之間的關(guān)系，既能突出重要關(guān)系，又能增強(qiáng)對(duì)材料行為的理解，也方便對(duì)材料作出選擇。不過，許多情況下，這些相關(guān)性本質(zhì)上是高度多維的，通常只能使用二維圖表分析來建立不同屬性之間的關(guān)系，可能僅表達(dá)了這些關(guān)系的某些方面。要使材料的高維數(shù)據(jù)可視化、可作有意義的比較分析困難不小。來自美國Lehigh大學(xué)的Jeffrey Rickman，采用可視化策略（即平行坐標(biāo)）的數(shù)據(jù)分析方法，更好地展示了多維材料數(shù)據(jù)，可以更好地識(shí)別不同屬性之間的有用關(guān)系。他以這種方法，構(gòu)建了金屬系和陶瓷系多維材料屬性圖表，并作了系統(tǒng)分析，簡化了高維幾何圖形的描述，實(shí)現(xiàn)了尺寸縮小和重要屬性之間關(guān)系的識(shí)別，強(qiáng)化了不同材料類別之間的區(qū)別，為識(shí)別材料各屬性之間的關(guān)系提供了強(qiáng)有力的工具。

It is often advantageous to display material properties relationships in the form of charts that highlight important correlations and thereby enhance our understanding of materials behavior and facilitate materials selection. Unfortunately, in many cases, these correlations are highly multidimensional in nature, and one typically employs low-dimensional cross-sections of the property space to convey some aspects of these relationships. To overcome some of these difficulties, in this work we employ methods of data analytics in conjunction with a visualization strategy, known as parallel coordinates, to represent better multidimensional materials data and to extract useful relationships among properties. We illustrate the utility of this approach by the construction and systematic analysis of multidimensional materials properties charts for metallic and ceramic systems. These charts simplify the description of high-dimensional geometry, enable dimensional reduction and the identification of significant property correlations and underline distinctions among different materials classes.
