Enter the x- and y-variables, define the gradient, select the scales to make similar, and enter the by variables.

You can graph the x and y-variables as individual pairs or you can graph every combination of the x-y variables. The y-variable is the variable that you want to explain or predict. The x-variable is a corresponding variable that might explain or predict changes in the y-variable. All columns must be numeric, and each x-y variable pair must have the same number of rows.

Select to display a separate graph for each pair of x and y-variables that you enter. In this worksheet, Debt Ratio is the y-variable and Age is the x-variable. The graph shows the relationship between debt ratio and age.

C1 | C2 |
---|---|

Age | Debt Ratio |

45 | 0.80298 |

40 | 0.12188 |

38 | 0.08511 |

Select to display a separate graph for each possible combination of x and y-variables that you enter. In this worksheet, Debt Ratio is the y-variable and Age and Income are the x-variables. Minitab creates two graphs, one that shows the relationship between debt ratio and age and another that shows the relationship between income and age.

C1 | C2 | C3 |
---|---|---|

Age | Debt Ratio | Income |

45 | 0.80298 | 45,000 |

40 | 0.12188 | 75,000 |

38 | 0.08511 | 52,000 |

Select how you want to define the color scale of the bins on the binned scatterplot.

- Frequency of binned data
- Select to define the gradient scale by the number of observations in the bin.
- Mean of variable
- Select to define the gradient scale by the value of a third variable.

Use the same scale across multiple graphs. These options become available when you enter more than one pair of columns in X-variable and Y-variable.

- Same X-scale
- Use the same x-scale across all graphs.
- Same Y-scale
- Use the same y-scale across all graphs.

Enter one or more grouping variables in By
variables to create a separate binned scatterplot for each level of the grouping variables. The columns that you enter can be numeric or text, and must be the same length as the columns in X-variable and Y-variable. The y-scales for each variable are the same across
the multiple binned scatterplots.

- Show all combinations
When you enter multiple By variables, Minitab enables the Show all combinations checkbox. Select this option to create a separate binned scatterplot for each combination of groups created by the By variables. If you do not select this option, Minitab creates a plot for each group of each By variable.

For example, the first By variable has 2 groups, Male and Female, and the second By variable has 2 groups, Employed and Unemployed. If you select Show all combinations, Minitab creates 4 separate plots for the combinations of Male/Employed, Male/Unemployed, Female/Employed, and Female/Unemployed. If you do not select Show all combinations, Minitab creates 4 separate plots for Male, Female, Employed, and Unemployed.
