The TBoxPlot component is a chart component which creates statistical charts called box plots (for background information on box plots please visit Fundamentals of Statistics). The principle of generating one or several box plots is quite simple: the data for the box plot is contained in a data table. Each column of the data table forms the basis of a box plot, thus a table with, for example, 5 columns results in 5 box plots which are arranged in the same order as the columns.

The application of TBoxPlot is straightforward: simply store your data in the internal data table of the component, and the data will be displayed as box plots automatically. The results can be panned, zoomed and displayed in various directions with various colors. More details can be found in the online help pages.

The unit BOXPLOT is part of the SDL Component Suite.
