Colormaps

Usage

The easychart package comes pre-loaded with the 83 colormaps available in matplotlib. Each of these can be assigned by name to the chart.cAxis to convert the colormap to the chart.colorAxis.stops of the relevant chart.

Note

Colormap names are case-insensitive

import easychart

chart = easychart.new("column")
chart.cAxis = "reds"
chart.plot([1, 2, 3, 4, 5, 6])
chart

Each colormap can be reversed by appending .reversed to its name.

import easychart

chart = easychart.new("column")
chart.cAxis = "reds.reversed"
chart.plot([1, 2, 3, 4, 5, 6])
chart

Each colormap can also be mirrored by appending .symmetric to its name.

import easychart

chart = easychart.new("column")
chart.cAxis = "reds.symmetric"
chart.plot([1, 2, 3, 4, 5, 6, 7])
chart

And .reversed and .symmetric can be used jointly.

import easychart

chart = easychart.new("column")
chart.cAxis = "reds.reversed.symmetric"
chart.plot([1, 2, 3, 4, 5, 6, 7])
chart
