Question

我收到的错误虽然数据看起来不错

ValueError: to_rgba: Invalid rgba arg "['g']" to_rgb: Invalid rgb arg "('g',)" sequence length is 1; must be 3 or 4

我将它加载到元组最后一个参数

sector_format = {
'0': ["Materials","o",'lightcoral'],
'1':["Information Technology","^",'g'],
'2':[ "Financials","v",'r'],
'3':["Consumer Discretionary","s",'c'],
'4':["Industrials","d",'m'],
'5':["Health Care","8",'y'],
'6':["Energy",">",'k'],
'7':["emerging markets","h",'lightgrey'],
'8':["Consumer Staples","|",'lightblue']
}

我在这里使用它，其中final_np [test：test + 1,3]包含颜色值

ax1.plot(final_np[prior_test:test,1],final_np[prior_test:test,2],lw = 0.5,color=final_np[test:test+1,3],marker=r"$ {} $".format(final_np[test:test+1,0]),markersize=final_np[test:test+1,6])

如果我打印出测试数据（这是一个例子）

print("test data ", final_np[prior_test:test,1],final_np[prior_test:test,2],final_np[test:test+1,0],final_np[test:test+1,6],final_np[test:test+1,3])

我将传递给颜色的值作为'r'，这对我来说似乎没问题。这是一个测试打印的例子

test data  [datetime.date(2015, 8, 10) datetime.date(2015, 8, 14)
 datetime.date(2015, 8, 17) datetime.date(2015, 8, 21)
 datetime.date(2015, 8, 24) datetime.date(2015, 8, 28)
 datetime.date(2015, 8, 31)] [64.0 90.0 89.0 8.0 5.0 50.0 53.0]
 ['^VIX']    [20] ['r']

我错过了什么？

@cphlewis你是一个明星！

这次让我再次看错了IN DETAIL，你是对的。我做了mod

 jcolor  = ''.join(final_np[test:test+1,3])

并用

调用情节

ax1.plot(final_np[prior_test:test,1],final_np[prior_test:test,2],lw = 0.5,color=jcolor,marker=r"$ {} $".format(final_np[test:test+1,0]),markersize=final_np[test:test+1,6])

所有人都在花园里。谢谢@cphlewis

matplotlib无效的rgba arg，但我正在通过正确的论证我“想”
