The following example uses the Fisher’s Iris data set (Mardia, Kent, and Bibby 1979). The Iris.jmp sample data table contains measurements of the sepal length and width and petal length and width in centimeters for three species of Iris flowers: setosa, versicolor, and virginica. To find characteristics that differentiate the three species, examine these measurements.

Open the Iris.jmp sample data table.
2.
Select Graph > Parallel Plot.
3.
Select Sepal length, Sepal width, Petal length, and Petal width and click Y, Response.
4.
Select the Scale Uniformly check box.
