from the above output of correlation matrixwe can see that it is symmetrical the bottom left is same as the top right it is also observed that each variable is positively correlated with each other scatter matrix plot scatter plots shows how much one variable is affected by another or the relationship between them with the help of dots in two dimensions scatter plots are very much like line graphs in the concept that they use horizontal and vertical axes to plot data points example in the following examplepython script will generate and plot scatter matrix for the pima indian diabetes dataset it can be generated with the help of scatter_matrix(function on pandas dataframe and plotted with the help of pyplot from matplotlib import pyplot from pandas import read_csv from pandas tools plotting import scatter_matrix path " :\pima-indians-diabetes csvnames ['preg''plas''pres''skin''test''mass''pedi''age''class'data read_csv(pathnames=namesscatter_matrix(datapyplot show(
