By default, the scale on the y-axis is in data units. For example, the y-axis values in the following line plot represent light output.

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

LightOutput | Temperature | GlassType |

580 | 100 | 1 |

1090 | 125 | 1 |

1392 | 150 | 1 |

550 | 100 | 2 |

- Right-click the graph and choose .
- Select Show Y as Percent, and choose one of the following options.
- Across all x-categories

- Within each x-category
- The sum of the plotted values within each x-category is 100%. Use this option if you want to standardize within categories and accentuate differences. For example, in this plot, the sum of the three plotted values at each level of Temperature is 100%.
