Matplotlib 1.5 axes.prop_cycle的用法 [英] Matplotlib 1.5 usage of axes.prop_cycle

问题描述

axes.color_cycle 。但是，它的用法非常简单：我们可以通过以下方式轻松获取特定颜色：

axes.color_cycle is deprecated in Matplotlib 1.5. However its usage was quite straightforward: we could easily grab a specific color by:

plt.rcParams['axes.color_cycle'][color_number]

axes.prop_cycle 支持以下语法：

ValueError: Can only use slices with Cycler.__getitem__

Cycler的文档不是很详细 http：// matplotlib.org/cycler/

And cycler doc is not very detailed http://matplotlib.org/cycler/

所以我不知道如何从prop_cycle中获得特定颜色。任何的想法？
谢谢

So I don't know how I can get a specific color from prop_cycle. Any idea? Thanks

推荐答案

获得所需的值：

list(mpl.rcParams['axes.prop_cycle'])[1]['color'])

有一个打开的 PR 要添加 by_key 方法用于 Cycler 对象，因此最终将是

There is an open PR to add a by_key method to Cycler objects so this will eventually be

mpl.rcParams['axes.prop_cycle'].by_key()['color'][1]

关于将颜色'c1'映射到 prop_cycle中的第一个颜色也有一些讨论。 ，但尚未实现。

There are also some discussions about mapping the color 'c1' to the first color in the prop_cycle, but that has not been implemented yet.

我是Cycler文档的主要作者，您还想在那里看到哪些其他详细信息？ ？

I am the main author of the cycler docs, what additional detail would you want to see there?
