本文记录了python中的数据可视化——散点图scatter,令x作为数据(50个点,每个30维),我们仅可视化前两维。labels为其类别(假设有三类)。 这里的x就用random来了,具体数据具体分析。 label设定为[1:20]->1, [21:35]->2, [36:50]->3,(python中数组连接方法:先强制转为list,用+,再转回array) 用matplotlib...

Let us get started. In this tutorial, we will learn 9 tips to make publication quality scatter plot with Python. We will start with how to make a simple scatter plot using Seaborn’s scatterplot() function. And then we will use the features of scatterplot() function and improve and make...
scatter(X[:,0] , X[:,1], c = y, alpha = 0.7); plt.subplot(1, 2, 2); plt.hist(y) plt.show() make_classification:可以在模拟数据中添加噪声 输入参数: sklearn.datasets.samples_generator.make_classification(n_samples=100, n_features=20, n_informative=2, n_redundant=2, n_repeated...
For example, there are simple functions for creating common chartslike the scatter plot, the bar chart, the histogram, and others. If you’re new to matplotlib and pyplot, I recommend that you check out some of our related tutorials: ...

你可以简单地将圆乘以你想要的半径。例如,对于5的半径: X5 = X*5 plt.scatter(X[:,0], X[:,1], label = "original") plt.scatter(X5[:,0], X5[:,1], label = "radius=5")...
