In built-in JMP platforms, the report layer is usually organized as an outline, but there are other kinds of organization available. For example, you could organize the information in tabs or panels. The display boxes in the report layer are nested-- they often contain, or are contained within, other display boxes. This nested or branched structure is called the display tree, and the display box at the root of the display tree contains all of the other boxes in the report layer. You can think of the display tree branching out from the root, so that lower branches are nested within higher branches. Let's talk about some of the different kinds of display boxes. Some display boxes are invisible, but their effect is clearly seen. For example, a vertical list box arranges the display boxes that are contained within it vertically. A vertical list box is made by calling the V List Box function with the nested display boxes as arguments. The order of the arguments determines the order of the display boxes within the display. An example of the use of the vertical list box is the series of outlines for the Summary of Fit, the Lack of Fit, and the Analysis of Variance in the Fit Least Squares platform. A horizontal list box arranges display boxes horizontally. A horizontal list box is made by calling the H List Box function with the nested display boxes as arguments. Like the V List Box function, the order of the arguments determines the order of the display boxes within the display. An example of the use of the horizontal list box is the series of outlines for each variable in the Distribution platform. A picture box is a kind of built-in display box that's used to present a graph. The display box shown here is made up of two axes and a frame in which the plot is drawn. The axis boxes themselves are made up of a scale and labels. And you can send messages to the frame box or axis boxes to change any of their characteristics or behaviors. You can make your own graphs by calling the Graph Box function. You use the arguments of this function to define properties like the name and scale of the axes. You can use the JSL graphics functions for custom drawing inside the frame box. Outlines are used throughout JMP platforms to organize information. You call the Outline Box function to make an outline item. The first argument is a character string that specifies the outline title, and the other arguments are display boxes nested in the outline item. Tables are another common element in JMP platforms. For example, the estimates of model parameters and their statistics shown here are presented in a table within the built in Parameter Estimates outline item in many platforms. You could make this table yourself by calling the Table Box function with arguments representing the columns of information to be presented. You would call the String Col Box function to present a column of text, for example, the column of terms. And you would call the Number Col Box function to present a column of numbers, for example, the estimates or the t ratios. The arguments to the string and number column boxes are a character string for the column header, followed by either a list of character values or a column vector of numeric values.
