Description

Format

Default value

axis_label

A list of two labels for the x and y axes.

Two Strings {x_label,y_label}.

{,}

close_right

When set to true, the histogram uses intervals closed on the right (i.e (a,b] ). When false uses intervals closed on the left.

Boolean

true

color

Sets the color of the outline of the histogram bars.

RGB list of values {r,g,b} where r, g, and b are integers between 0-255. Alternatively one of the following strings: black, white, red, green, blue, cyan, magenta, yellow, brown, orange, pink, grey, dark_grey, light_grey, or one of the HTML colors, by name (e.g. html_indigo rather than 4b0082).

{180,60,0}

fill_color

Sets the color of the inside of the histogram bars.

Same as the color option above.

{255,200,0}

frequencies

When set to true, the y-axis shows the absolute frequency of the values on the x-axis. When false the y-axis shows relative frequency.

Boolean.

true

intervals

Use this option to specify where histogram bars are delimited.

List of the exact values where histogram bars start and end, an algorithm that computes those values ("Sturges", "FD" or "Scott"), or a suggested number of boxes.

"Sturges"

show_axis

When set to true, shows both x and y axes. If false, shows no axes.

Boolean.

true

"" (empty string)

x_limits

List of two numbers to be used as the minimum and maximum values displayed on the x-axis.

{}

y_limits

List of two numbers to be used as the minimum and maximum values displayed on the y-axis.

Two Floats {a,b}

{}
