Graph Zones

The main element in the Graph Builder window is the graph area. The graph area contains zones, and you drag and drop variables from the Variables box into the zones.

Tip: If you drop variables into the center of the graph, JMP guesses which drop zone to put them into, based on whether the variables are continuous, ordinal, or nominal.

There are two types of zones into which you can drag variables:

•

Data zones include X, Y, Map Shape, Freq, Color, Size, and Interval. The X, Y, and Map Shape zones are positional, and influence the types of graph elements that are available. The Freq, Color, Size, and Interval zones modify certain graph elements.

•

Grouping zones partition the data into subsets that repeat the graph for each possible subset. Grouping zones include Group X, Group Y, Wrap, Overlay, and Page.

The following zones are available in Graph Builder:

Zone

Description

X and Y

Constructs plots that are based on the values, levels, or categories of the variables that you drop into these zones. Use the X zone for a horizontal layout and the Y zone for a vertical layout.

Group X and Group Y

Stratifies your data by the levels of the nominal or ordinal variable and constructs a plot for each level. Group X produces a horizontal display, and Group Y produces a vertical display.

The type of variable that you put in Group X or Y also determines aspects of the display:

•

Adding a continuous variable creates non-overlapping interval subgroups and plots for the values in each interval.

•

Adding a categorical variable creates plots for each level of the categorical variable.

You can add multiple variables to Group X or Group Y:

•

To add a variable above a variable in one of the Group zones, drag it to the left of that variable in the Group X zone or above that variable in the Group Y zone.

•

To add a variable below a variable in one of the zones, drag it to the right of that variable in the Group X zone or below that variable in the Group Y zone.

To stratify by the levels of two variables, drag a variable into both Group X and Group Y. To change the number of levels that appear, right-click in the axis border and select Levels in View. For a description of all options, see Options for Axes, Variable Labels, or Graph Titles.

Map Shape

Adds a map. Your variable must contain geographic place names, such as countries, regions, states, or provinces, or you must provide information in a custom shape file. Note the following:

•

If you drag and drop columns labeled Latitude and Longitude, JMP automatically assigns them to the Y and X roles (respectively).

•

When you drop a variable into the Map Shape zone, the X and Y zones disappear.

•

The Map Shape element can be used with the Points element to place points within the shape.

For more details about creating map shapes, see Map Shapes and Graph Builder in Create Maps.

Wrap

Creates rows of plots for the levels of a categorical variable or for the interval subgroups of a continuous variable. Use Wrap when your stratifying variable has many levels. To change the number of levels that appear, right-click in the axis border and select Levels in View. For a description of all options, see Grouping Zones Options.
