TRUE if gridlines in the vertical directions are to be drawn; FALSE otherwise (default = FALSE). |

`gridY` |
TRUE if gridlines in the horizontal directions are to be drawn; FALSE otherwise (default = FALSE). |

`data` |

logAxis is a wrapper function for performing calculations

logAxis.plot is the actual plotting function (which is called one axis at a time).

### Value
