使用RGB 字典进行颜色定义可能没有直接使用十六进制颜色来创建 colormap 更直观且易理解。当然自定义 colormap 的方式很多,而且都能达到要求。
Choosing Colormaps in Matplotlib Matplotlib has a number of built-in colormaps accessible via matplotlib.colormaps. There are also external libraries that have many extra colormaps, which can be viewed in the Third-party colormaps section of the Matplotlib documentation. Here we briefly discuss how...
Get a colormap instance, defaulting to rc values if name is None. Colormaps added with register_cmap() take precedence over built-in colormaps. If name is a matplotlib.colors.Colormap instance, it will be returned. If lut is not None it must be an integer giving the number of entries...

参考:matplotlib colormaps names Matplotlib是Python中最流行的数据可视化库之一,它提供了丰富的色彩映射表(Colormaps)选项,可以帮助我们更好地展示数据。本文将深入探讨Matplotlib中的色彩映射表,包括其名称、使用方法和自定义技巧。 1. 什么是色彩映射表?
在matplotlib库中,并不存在名为colormaps的直接属性。通常,色彩映射(colormaps)是通过matplotlib.cm模块或matplotlib.pyplot的colormap函数来访问的。 正确的属性或方法名称: 要访问matplotlib中的色彩映射,您应该使用matplotlib.cm模块中的函数或属性,或者通过matplotlib.pyplot.colormap(尽管后者更常用于设置当前绘图的色彩...
