This scale is given with the help of a color-bar on the right side of the plot. Adding title and labels to the plot We can tweak the generated correlation matrix, just like any other Matplotlib plot. Let us see how we can add a title to the matrix and labels to the axes. correlati...
plt.show() 与(3)类似,在这里注意可以共享x轴和y轴,用了sharex=False, sharey=False的命令。 (5)相关系数矩阵图(Correlation Matrix Plot) import numpy correlations = data.corr() #计算变量之间的相关系数矩阵 # plot correlation matrix fig = plt.figure() #调用figure创建一个绘图对象 ax = fig.add...
