The Plot-Data Interface in Statistical Graphics
本文讨论了统计软件中绘图模块与数据模块之间的接口问题，提出通过构建绘图-数据接口来应对多种绘图类型和数据表示带来的复杂性。
Statistical software systems include modules for manipulating data sets, model fitting, and graphics. Because plots display data, and models are fit to data, both the model-fitting and graphics modules depend on the data. Today's statistical environments allow the analyst to choose or even build a suitable data structure for storing the data and to implement new kinds of plots. The multiplicity problem caused by many plot varieties and many data representations is avoided by constructing a plot-data interface.
