我正在尝试绘制具有独特颜色的聚类，但出现错误 [英] I am trying to plot clusters with unique color but getting error

问题描述

我只是想绘制x，y，然后用聚类为它们着色.每个群集应具有唯一的颜色.但是我出错了.我尝试不使用 numpy 数组，但仍然出错.

I am just trying to plot x, y and then color them with clusters. Each cluster should have unique color. But i am getting error. I tried without using numpy array but still getting error.

" c 的形状 (5113,) 不能作为 x 大小为 5113、y 大小为 5113 的颜色序列""

" c of shape (5113,) not acceptable as a color sequence for x with size 5113, y with size 5113""

x = np.array(df['ip_indexed'])
print(x.shape)
y = np.array(df['geohash_indexed'])
print(y.shape)
labels = np.array(df['clusters'])
print(labels.shape)

''' output. 
(5113,)
(5113,)
(5113,)

LABEL_COLOR_MAP = {9066 : 'r',
               9068: 'silver',
               17182 : 'k',
               17183: 'c',

               17189:'deeppink'
               }

label_color = np.array([LABEL_COLOR_MAP[l] for l in labels])
label_color.shape

plt.figure(figsize=(50, 10))
plt.xlabel("ip_address", fontsize= 20)
plt.ylabel("geohash", fontsize= 20)
plt.title("clusters", fontsize= 50)
colors = np.random.rand(5113)
plt.scatter(x, y , c = label_color)

ValueError: c of shape (5113,) not acceptable as a color sequence for x with size 5113, y with size 5113

推荐答案

我刚才遇到了同样的问题，在寻找解决方案时偶然发现了这篇文章.我可以肯定地说的话:在 plt.scatter(x, y , c = label_color) 行中，x、y 和 c必须相同，我相信，如果这三个都是熊猫数据框，那么这三个都是最好的.我所有成功对象的形状都是 (5113, 1) 而不是你的 (5113,).我知道您正在 print() 语句中测试形状，但似乎有些不对劲.

I was facing the same issue moments ago and stumbled across this post in searching for a solution. Things that I can definitively say: In the line plt.scatter(x, y , c = label_color) the shape of x, y, and c needs to be the same and, I believe, all three are best if they are a pandas dataframe. The shape of all of my successful objects was (5113, 1) rather than your (5113,). I recognize that you are testing the shape in your print() statements, but something seems amiss.

我绝不是专业人士，在某些方面我可能是错的，但这就是我提出自己的解决方案的方式.希望它可以在正确的方向上推动您和其他人.

I am by no means a professional and I may be wrong in some of this, but this was how I came to my own solution. Hopefully it might nudge you and others in the right direction.
