Use a 3D scatterplot to explore the potential relationships among three variables. When you create a 3D scatterplot, you usually display predictor variables on the x-axis and the y-axis and the response variable on the z-axis. For example, you may want to examine how temperature and humidity affect the drying time of paint, or how horsepower and tire pressure affect a vehicle's fuel efficiency.
Use a 3D surface plot to examine the relationship between a response variable (Z) and two predictor variables (X and Y), by viewing a three-dimensional surface of the predicted response. You can choose to represent the predicted response as a smooth surface or a wireframe.
The following images show elements that you can display on a 3D graph. To select elements when you create the graph, click Data View.
For information on adding or changing the grouping variables for an existing graph, go to Display groups on graphs.
For more information on editing these graph features, including how to change a surface plot to a wireframe plot, go to the following topics.
You can rotate a 3D graph to view them from different angles. This allows you to more thoroughly explore the relationships among the variables. Use the buttons on the toolbar in graph editing mode to rotate 3D graphs. These buttons appear when a 3D scatterplot or a 3D surface plot is active.
Toolbar item | Action |
---|---|
Rotate the graph clockwise or counterclockwise about the x-axis. | |
Rotate the graph clockwise or counterclockwise about the y-axis. | |
Rotate the graph clockwise or counterclockwise about the z-axis. |
When you click a button, a preview window pops up to show exactly how the graph will spin.
You can select between a solid surface and a wireframe.
You can specify the surface color, wire color, and wire size.
For information on how to change the appearance of the mesh of a surface plot by using different methods to interpolate between values, go to Mesh.
