Pearson correlation coefficient scatter plot

Introduction
Pearson correlation coefficient was used to reflect the linear-related degrees of two variables. It's range is -1 to 1. 1 depicts totally positive correlated; -1 depicts totally negative correlated; 0 depicts no linear correlation.
Input data instructions
Matrix input data, names are uniqe. The first column is name, and the other columns are values. If input two datasets, scatter plot will be show, otherwize, correlation matrix will output, you can copy the input and paste to correlation plot to perform a matrix plot.
