Enlarges or shrinks the 3D scatterplot.<br />

Changes the view of the scatterplot from 3-dimensional to an orthographic<br />

projection. In the orthographic view, the walls of the scatterplot do not<br />

converge to a vanishing point. This means that you can compare near <strong>and</strong><br />

far distances <strong>and</strong> see the structure between data points.<br />

Note: If you turn off orthographic view <strong>and</strong> completely decrease the<br />

perspective, the walls of the scatterplot do not converge. This is the same<br />

effect that you get when you turn on orthographic view.<br />

Increases or decreases the perspective. Large values create a view that is<br />

unnaturally large <strong>and</strong> visually disorienting. In this case, you need to resize<br />

the scatterplot window to show the entire plot.<br />

Increases or decreases the size of the data point markers.<br />

Increases <strong>and</strong> decreases the data marker quality. For example, when you<br />

increase the marker quality, some markers have an opaque center. Other<br />

symbol markers are formatted in bold. Increase the zoom to see these<br />

changes in quality.<br />

Increases or decreases the transparency of the data markers.<br />

Increases or decreases the text size.<br />

Changes the width of the coordinate <strong>and</strong> axes lines.<br />

Additional Examples of the Scatterplot 3D Platform<br />

This section contains additional examples using 3D scatterplots.<br />

Example of an Ungrouped Normal Contour Ellipsoid<br />

This example shows how to add a normal contour ellipsoid to more than 75% of the data points. The<br />

ellipsoid is 25% transparent.<br />

1. Open the Iris.jmp sample data table.<br />

2. Select Graph > Scatterplot 3D.<br />

3. Select Sepal length, Sepal width, Petal length, <strong>and</strong> Petal width <strong>and</strong> click Y, Columns.<br />

4. Click OK.<br />

5. From the red triangle menu, select Normal Contour Ellipsoids. Notice that Ungrouped is already<br />

selected.<br />

6. Type 0.75 next to Coverage.
