## Arguments

x |
The value vector. The value can be a vector or a matrix. The length of the vector or the number of rows of the matrix is taken as the number of the observations of the annotation. |

which |
Whether it is a column annotation or a row annotation? |

border |
Wether draw borders of the annotation region? |

gp |
Graphic parameters for lines. The length of each graphic parameter can be 1, or number of columns of `x` is `x` is a matrix. |

add_points |
Whether to add points on the lines? |

smooth |
If it is `TRUE` , smoothing by `loess` is performed. If it is `TRUE` , `add_points` is set to `TRUE` by default. |

pch |
Point type. The length setting is the same as `gp` . |

size |
Point size, the value should be a `unit` object. The length setting is the same as `gp` . |

pt_gp |
Graphic parameters for points. The length setting is the same as `gp` . |

ylim |
Data ranges. By default it is `range(x)` . |

extend |
The extension to both side of `ylim` . The value is a percent value corresponding to `ylim[2] - ylim[1]` . |

axis |
Whether to add axis? |

axis_param |
parameters for controlling axis. See `default_axis_param` for all possible settings and default parameters. |

width |
Width of the annotation. The value should be an absolute unit. Width is not allowed to be set for column annotation. |

height |
Height of the annotation. The value should be an absolute unit. Height is not allowed to be set for row annotation. |

## Value

An annotation function which can be used in `HeatmapAnnotation`

.
