Module Contents

my_code_base.plot.colors.build_continuous_cmap(hex_list, float_list=None, N=256, name='my_cmap')

Create and return a color map that can be used in heat map figures. If float_list is not provided, colour map graduates linearly between each color in hex_list. If float_list is provided, each color in hex_list is mapped to the respective location in float_list.

Parameters:

• hex_list (list of hex code strings)

• float_list (list of floats between 0 and 1, same length as hex_list. Must start with 0 and end with 1.)

Return type:

colour map

my_code_base.plot.colors.hex_to_rgb(value)

Convert hex to rgb colors

Parameters:

value (string) – String of 6 characters representing a hex colour.

Returns:

list length 3 of RGB values

Return type:

tuple

Examples

>>> hex_to_rgb('#f00')   # red
(255, 0, 0)
>>> hex_to_rgb('fff')    # white
(255, 255, 255)

my_code_base.plot.colors.rgb_to_dec(value)

Convert rgb to decimal colours (i.e. divides each value by 255)

Parameters:

value (list (length 3) of RGB values)

Returns:

list (length 3) of decimal values

Return type:

tuple[float]

Example

>>> rgb_to_dec((255, 0, 0))
(1.0, 0.0, 0.0)
