ly_hist: Add a "hist" layer to a Bokeh figure

Description Usage Arguments Handling color Handling alpha Additional parameters See Also Examples

View source: R/layer_stats.R


Draws a histogram


ly_hist(fig, x, data = figure_data(fig), breaks = "Sturges", freq = TRUE,
  include.lowest = TRUE, right = TRUE, color = NULL, alpha = 1,
  lname = NULL, lgroup = NULL, visible = TRUE, ...)



figure to modify


either a vector to be passed to hist or an object of class "histogram"


an optional data frame, providing the source for x

breaks, freq, include.lowest, right

parameters passed to hist


color for the glyph - a hex code (with no alpha) or any of the 147 named CSS colors, e.g 'green', 'indigo' - for glyphs with both fill and line properties, see "Handling color" below


the alpha transparency of the glyph between 0 (transparent) and 1 (opaque) - if glyph has both fill and color properties, see "Handling alpha" below


layer name


layer group


should the layer be visible?


additional parameters for fine control over fill and line properties (see "Additional parameters" below)

Handling color

The color parameter is a high-level plot attribute that provides default behavior for coloring glyphs.

When color is NULL and fill_color or line_color are not specified, the color will be chosen from the theme.

Handling alpha

The alpha is a high-level plot attribute that sets the transparency of the glyph being plotted.

Additional parameters

fill_color color to use to fill the glyph with - a hex code (with no alpha) or any of the 147 named CSS colors, e.g 'green', 'indigo'
fill_alpha transparency value between 0 (transparent) and 1 (opaque)
line_color color to use to stroke lines with - a hex code (with no alpha) or any of the 147 named CSS colors, e.g 'green', 'indigo'
line_width stroke width in units of pixels
line_alpha transparency value between 0 (transparent) and 1 (opaque)
line_join how path segments should be joined together 'miter' 'round' 'bevel'
line_cap how path segments should be terminated 'butt' 'round' 'square'
line_dash array of integer pixel distances that describe the on-off pattern of dashing to use
line_dash_offset the distance in pixels into the line_dash that the pattern should start from
