You can create a graph like the following example using data arranged in different layouts in the worksheet.

To create a line plot without symbols, choose the layout option that is similar to your worksheet.

Follow these steps if your worksheet contains a column of measurement data and two columns of categorical data for grouping.

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

Reading | Compound | Octane |

0.213751 | 900 | 84.9 |

0.236162 | 920 | 84.9 |

0.211233 | 940 | 84.9 |

0.226918 | 980 | 84.9 |

- Choose .
- Under Without Symbols, choose One Y, then click OK.
- Under Function, choose the function of the graph variable that you want to graph. In the example, Mean is the function.
- Under Graph variables, enter a column of numeric or date/time data. In the example, Reading is the graph variable.
- Under Categorical variable for X-scale grouping, enter a column of categorical data for the x-axis scale. In the example, Compound is the categorical variable for x-scale grouping.
- Under Categorical variable for legend grouping, enter a column of categorical data to be defined in the legend. In the example, Octane is the categorical for legend grouping.
- Click OK.

Follow these steps if your worksheet contains multiple columns of measurement data and each column is a group, plus a column of categorical data for grouping.

- Choose .
- Under Without Symbols, choose Multiple Y's, then click OK.
- Under Function, choose the function of the graph variable that you want to graph. In the example, Mean is the function.
- Under Graph variables, enter multiple columns of numeric or date/time data. In the example, 900 through 1600 are the graph variables.
- Under Categorical variable for grouping, enter a column of categorical data. In the example, Octane is the categorical variable for grouping.
- Click OK.

Follow these steps if your worksheet contains multiple columns of summarized data. You can have a corresponding column of row labels (optional).

C1 | C2 | C3 | C4 | C37 |
---|---|---|---|---|

900 | 920 | 940 | ... | Octane |

0.213751 | 0.236162 | 0.211233 | .... | 84.9 |

- Choose .
- Under Without Symbols, choose Series in Rows or Columns, then click OK.
- Under Graph variables, enter multiple columns of summarized numeric or date/time data. In the example, 900 through 1600 are the graph variables.
- Under Label column (optional), enter a column of categorical values that corresponds to the rows. In the example, Octane is the label column. If you don't enter a label column, Minitab uses the row numbers as labels.
- Under Series Arrangement, choose the arrangement to graph. In the example, Each row forms a series is the arrangement. The series that you choose (row or column) appears in the graph legend, and the other appears as the X-scale label.
- Click OK.
