我正在尝试绘制散点图，其中散点图中的每个点都应对应于我选择的给定颜色的特定阴影。mpl 文档指出，如果我设置类似：
color = '0.7'
它给了我一个灰色阴影，其缩放强度为0.7. 我正在从值在 0 到 1 之间的数组中读取颜色的强度，每个值对应于散点图中该点的强度。我的代码如下：
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
import math
tsne_embeddings = np.load("tsne_embeddings.npy")
labels = np.load('labels.npy')
weights = np.load('weights.npy')
# Scale the weights from 0 to 1
max_weight = max(weights)
min_weight = min(weights)
weights = (weights - min_weight)/(max_weight - min_weight)
print(tsne_embeddings.shape)
x = list(tsne_embeddings[:,0])
y = list(tsne_embeddings[:,1])
labels = list(labels)
weights = np.round(weights,decimals=2)
weights = (np.exp(weights) - 1)/(np.exp(1) - 1) …
