plt.scatter(a,aa,color=aaa)
plt.colorbar()
plt.show()

我收到了这个错误：

ValueError: to_rgba: Invalid rgba arg "27114"
to_rgb: Invalid rgb arg "27114"
cannot convert argument to rgb sequence

我怎么能用第三个数据添加colorbar？

Answer 1

您的变量aaa未定义matplotlib颜色。来自documentation：

Matplotlib识别以下格式以指定颜色：


[0,1]中浮点值的RGB或RGBA元组（例如，（0.1,0.2,0.5）或（0.1,0.2,0.5,0.3））;

十六进制RGB或RGBA字符串（例如，'＃0F0F0F'或'＃0F0F0F0F'）;

[0,1]中浮点值的字符串表示，包括灰度级（例如，'0.5'）;

{'b'，'g'，'r'，'c'，'m'，'y'，'k'，'w'}之一;

一个X11 / CSS4颜色名称;

来自xkcd颜色调查的名称;以'xkcd：'为前缀（例如'xkcd：sky blue'）;

其中一个{'tab：blue'，'tab：orange'，'tab：green'，'tab：red'，'tab：purple'，'tab：brown'，'tab：pink'，'tab ：grey'，'tab：olive'，'tab：cyan'}，它们是'T10'分类调色板中的Tableau颜色（这是默认的颜色循环）;

“CN”颜色规范，即“C”后跟单个数字，这是默认属性循环的索引   （matplotlib.rcParams [ 'axes.prop_cycle']）;索引发生在   艺术家创作时间，如果周期没有，则默认为黑色   包括颜色。

这意味着您需要转换数字以符合其中一种格式。
