Select the Advanced tab of the 3D Range Plots Startup Panel to specify the variables to use in your graph, as well as select from a variety of graph types and the mode of graph to use.

Variables. Click the Variables button to display a standard variable selection dialog box, in which you select the variables used to define the middle point and range (i.e., the lower limit and upper limit values). The selection made will be displayed to the right of the Variables button. If more than one variable is selected for the middle point list, a multivariate range graph will be produced (the same number of variables must be selected in the mid-point and range lists).

Graph type. Select one of six types of 3D range plots to be plotted from the Graph type list on this tab. Click a link below for a brief description of that type of graph.

Mode (range values). You can interpret the values of variables selected for the ranges in two different ways:

Absolute. When you select this option button, the actual values of the middle point, minimum, maximum values will be plotted. For example, for a middle point value of 9, a minimum value of 1, and a maximum value of 12, the absolute range (as indicated by whiskers, boxes, or columns, see above) would start at 1 and end at 12, with the middle point at 9.

Relative to Mid-Point. Select this check box to display the range (as indicated by whiskers, boxes, or columns, see above) relative to the middle point value. For the three points given in the above example, the range relative to the mid-point would start at 8 (the value that is 1 less than the mid-point of 9) and end at 21 (the value that is 12 more than the mid-point) with the mid-point at 9.
