Example 5: Outliers in scatter plots Unusual points, or outliers, in the data stand out in scatter plots. Figure 5 shows a scatter plot with an outlier, while Figure 6 shows the same data without the outlier. The single outlier in the upper right corner has an impact on your ability to...
3. 散点矩阵图(Scatter Matrix Plot) 用于可视化多个变量之间的关系,通过绘制多个散点图组合在一起形成一个矩阵 代码语言:javascript 代码运行次数:0 运行 AI代码解释 import matplotlib.pyplot as plt import numpy as np # 生成随机数据 np.random.seed(0) data = np.random.rand(4, 100) # 生成一个4行...
For example in Figure 2.16(d) we can clearly see that the dominant axes of the seismic data distribution are not perpendicular. In fact, in the scatterplots uncorrelated non-Gaussian mixtures, the dominant axes of data are not collinear with the axes of the 2D plot, and they are not ...
To plot each circle with a different size, specify sz as a vector or a matrix. example scatter(x,y,sz,c) specifies the circle colors. You can specify one color for all the circles, or you can vary the color. For example, you can plot all red circles by specifying c as "red". ...
scatter_matrix(data, axs=axs) plt.show() 在这个示例中,我们首先导入NumPy和Matplotlib库。然后,我们使用NumPy的random.rand函数创建一个20x4的随机数据矩阵。接下来,我们使用scatter_matrix函数创建散点矩阵图,并将结果存储在变量scatter_matrix中。scatter_matrix函数的第一个参数是要可视化的数据,第二个参数是一个...
Scatter Plot Matrix 又叫 Scagnostic. 是一种常用的高纬度数据可视化技术。它将高纬度的数据每两个变量组成一个散点图,再将他们按照一定的顺序组成散点图矩阵。通过这样的可视化方式,能够将高纬度数据中所有的变量两两之间的关系展示出来。 上图,用scatter plot matrix 展示了 安德森鸢尾花卉数据集(Anderson’s Iri...
矩阵散点图(Matrix Scatter Plot)是散点图的扩展,当欲同时观察多个变量间的相关关系时,若一一绘制它们间的简单散点图,十分麻烦。此时可利用散点图矩阵来同时绘制各自变量间的散点图,这样可以快速发现多个变量间的主要相关性,这一点在进行多元线性回归时显得尤为重要,它从一定程度上克服了在平面上展示高维数据的困难...
About using a Scatterplot Matrix To find the plot or correlation for any two attributes, look at where their rows and columns intersect. For example, for three attributes the matrix is organized as follows: Mousing over a chart or a correlation value highlights the attributes being compared. ...
