You can create a 3D scatterplot that represents the relationship between three variables and includes groups represented by different symbols.

To create a 3D scatterplot with overlaid groups, you must use a worksheet that contains three columns of measurement data: one response variable (Z) and two predictor variables (X and Y), and a categorical variable for grouping.

C1 | C2 | C3 | C4-T |
---|---|---|---|

Temp | Time | Quality | Operator |

350 | 24 | 0.1 | A |

350 | 26 | 0.2 | B |

350 | 28 | 1.1 | A |

- Choose .
- Choose With Groups, then click OK.
- Under Z variable, enter the response variable. In the example, Quality is the Z variable.
- Under Y variable, enter the predictor variable to appear on the Y-axis. In the example, Temp is the Y variable.
- Under X variable, enter the predictor variable to appear on the X-axis. In the example, Time is the X variable.
- Under Categorical variables for grouping (0-3), enter a categorical variable. In the example, Operator is the categorical variable for grouping.
- Click OK.
