## Arguments

x |
A matrix or a list. If `x` is a matrix and if `which` is `column` , statistics for boxplots are calculated by columns, if `which` is `row` , the calculation is done by rows. |

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

type |
Type of graphics to represent density distribution. "lines" for normal density plot; "violine" for violin plot and "heatmap" for heatmap visualization of density distribution. |

heatmap_colors |
A vector of colors for interpolating density values. |

joyplot_scale |
Relative height of density distribution. A value higher than 1 increases the height of the density distribution and the plot will represented as so-called "joyplot". |

border |
Wether draw borders of the annotation region? |

gp |
Graphic parameters for the boxes. The length of the graphic parameters should be one or the number of observations. |

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`

.
