## Histogram Annotation

### Description

Histogram Annotation

### Usage

    anno_histogram(x, which = c("column", "row"), n_breaks = 11,
        border = FALSE, gp = gpar(fill = "#CCCCCC"),
        axis = TRUE, axis_param = default_axis_param(which),
        width = NULL, height = NULL)

### 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?
`n_breaks` | Number of breaks for calculating histogram.
`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`.

### Examples

    m = matrix(rnorm(1000), nc = 10)
    anno = anno_histogram(t(m), which = "row")
    draw(anno, test = "row histogram")
    anno = anno_histogram(t(m), which = "row", gp = gpar(fill = 1:10))
    draw(anno, test = "row histogram with color")
    anno = anno_histogram(t(m), which = "row", n_breaks = 20)
    draw(anno, test = "row histogram with color")
