A continuation from my previous post, this time we are going to do more charting to find correlations between multiple stocks. If you have several numeric variables and want to visualize their distributions together, you have 2 options: plot them on the same axis (left), or split your windows in several parts ( faceting, right). The data can than be seen as a 2D table, or matrix, with columns giving the different attributes of the data, and rows the observations. If you're looking for a simple way to implement it in R, pick an example below. These graphs are able to convey a lot of information, while also being visually appealing. I used the seaborn.
