How to color `matplotlib` scatterplot using a continuous value [`seaborn` color palettes?]

问题 I have a scatterplot and I want to color it based on another value (naively assigned to np.random.random() in this case). Is there a way to use seaborn to map a continuous value (not directly associated with the data being plotted) for each point to a value along a continuous gradient in seaborn ? Here's my code to generate the data: import numpy as np import pandas as pd import matplotlib.pyplot as plt from sklearn.datasets import load_iris from sklearn.preprocessing import StandardScaler

问题 I want to make a UIView have an effect of transparent gradient from the middle to the left and right. Like in this example: The word 籍 has the desired effect. This view is achieved by the class MarqueeLabel. I examined the source code, it is likely implemented by class CALayer . 回答1: You can use CAGradientLayer as following. gradientLayer = [CAGradientLayer layer]; gradientLayer.frame = baseView.bounds; gradientLayer.startPoint = CGPointMake(0.5,0.0); gradientLayer.endPoint = CGPointMake(0.5
