Use this to produce a biplot of the results from correspondence or multiple correspondence analysis.

## Available data

This lists data structures appropriate to the current input field. It lists texts for use in specifying the labels for the rows and/or the columns. Double-click a name to copy it to the current input field or type the name.

## Display in plot

Specifies which scores to display in the graph.

Row scores |
Plots the row scores obtained in the analysis. |

Column scores |
Plots the column scores obtained in the analysis. |

## Scaling

Type of scaling to use when plotting the row scores and column scores.

**Row**:

Principal coordinates |
Plots the row scores, scaled so that they have inertia equal to the latent roots of the data. |

Standard coordinates |
Plots the row scores, scaled so that they have inertia equal to one. |

Standard coordinates x row mass |
Plots the row standard coordinates multiplied by the row mass. |

Standard coordinates x sqrt(row mass) |
Plots the row standard coordinates multiplied by the square root of the row mass. |

**Column**:

Principal coordinates |
Plots the column scores, scaled so that they have inertia equal to the latent roots of the data. |

Standard coordinates |
Plots the column scores, scaled so that they have inertia equal to one. |

Standard coordinates x column mass |
Plots the column standard coordinates multiplied by the column mass. |

Standard coordinates x sqrt(column mass) |
Plots the column standard coordinates multiplied by the square root of the column mass. |

Note that at least one of the row or column lists has to be set to principal coordinates.

## Colour symbols based on inertia for

Whether the colour of the row and/or column scores is different for differing levels of row and/or column inertia (i.e. smaller inertias cause transparent symbols to be plotted).

## Size symbols based on mass for

Whether the size of the symbol for the row and/or column scores is different for differing row and/or column masses (i.e. larger masses produce larger symbols).

## Labels for row scores

Can be used to specify what type of labels to use to identify the row scores on the plot. Select **Numbers** to display the unit numbers, **None** for no labels, **Unit labels** to display the unit labels, or **Labels** to supply alternative labels using the name of a text structure in the space provided.

## Labels for column scores

Can be used to specify what type of labels to use to identify the column scores on the plot. Select **Numbers** to display the unit numbers, **None** for no labels, **Unit labels** to display the unit labels, or **Labels** to supply alternative labels using the name of a text structure in the space provided.
