Overview

A rotating plot is a three-dimensional scatter plot. If the Z variable is a response to predictor variables X and Y, it makes sense to fit a response surface to the data.

To create a rotating plot using the GUI

1. Open or create a data table.

   For details, see Creating a Data Table.

2. Make sure the data table window is the active window.
3. On the Graph menu, click Rotating Plot.

   IML Studio displays the Rotating Plot dialog box.

4. Select a numeric variable and click Set Z.

   If you wish to fit a response surface to the scatter plot, the Z variable should be the response variable.

5. Select a numeric variable and click Set Y.
6. Select another numeric variable and click Set X.

   If you wish to fit a response surface to the data, the X and Y variables should be predictor variables.

7. Click OK.
