- class plotnine.scales.scale_color_brewer(type='seq', palette=1, direction=1, **kwargs)¶
Sequential, diverging and qualitative discrete color scales
['seq', 'div', 'qual']
Type of data. Sequential, diverging or qualitative
If a string, will use that named palette. If a number, will index into the list of palettes of appropriate type. Default is 1
- direction: int in ``[-1, 1]``
Sets the order of colors in the scale. If 1, the default, colors are as output by mizani.palettes.brewer_pal(). If -1, the order of colors is reversed.
- breaksarray_like or
Major break points. Alternatively, a callable that takes a tuple of limits and returns a list of breaks. Default is to automatically calculate the breaks.
Multiplicative and additive expansion constants that determine how the scale is expanded. If specified must be of length 2 or 4. Specifically the values are in this order:
(mul, add) (mul_low, add_low, mul_high, add_high)
(0, 0)- Do not expand.
(0, 1)- Expand lower and upper limits by 1 unit.
(1, 0)- Expand lower and upper limits by 100%.
(0, 0, 0, 0)- Do not expand, as
(0, 0, 0, 1)- Expand upper limit by 1 unit.
(0, 1, 0.1, 0)- Expand lower limit by 1 unit and upper limit by 10%.
(0, 0, 0.1, 2)- Expand upper limit by 10% plus 2 units.
If not specified, suitable defaults are chosen.
Name used as the label of the scale. This is what shows up as the axis label or legend title. Suitable defaults are chosen depending on the type of scale.
str. Labels at the breaks. Alternatively, a callable that takes an array_like of break points as input and returns a list of strings.
- limitsarray_like, optional
Limits of the scale. Most commonly, these are the min & max values for the scales. For scales that deal with categoricals, these may be a subset or superset of the categories.
str. Aesthetics covered by the scale. These are defined by each scale and the user should probably not change them. Have fun.
Whether to drop unused categories from the scale
Truetranslate missing values and show them. If
Falseremove missing values. Default value is
Color of missing values. Default is
