一个复合散点图和轮廓过程的基础上使用的非参数或参数的二元密度估计作为数据转换。每个转换值确定用于表示每个单独基准的字符（符号的形状）、颜色和遮罩（字符是否出现在图中）。这有利于搜索全局分布特征，而不会忽视这样一个事实：人们正在处理的是估计量，而不是真实基础分布的假设表示。一个单一的数据与一个单一的数据点的关联进行检查，并描述了一个应用程序，其中一个喷雾组成的一个可变数量的单独的显示点替代传统的数据点。
A composite scatter diagram and contouring procedure is presented based on the use of a nonparametric or parametric bivariate density estimator as a data transformation. Each transformed value determines the character (shape of the symbol), color, and masking (whether or not the character is to appear in the plot) to be used to represent each individual datum. This facilitates the search for global distributional characteristics, without the danger of losing sight of the fact that one is dealing with an estimator and not a hypothesized representation of a true underlying distribution. The association of a single datum with a single data point is examined and an application is described where a spray consisting of a changeable number of individual display points substitutes for the conventional data point.
