  <p>I have this <a href="http://www.chartologic.com/php/foo.csv" rel="nofollow noreferrer">data</a> which is 1940 x 4 in its dimensions. Its rows are readings or samples while its columns are variables (temp, humid, windspeed and pressure). I wanted to conduct a PCA Analysis and to plot its results using Python. The situation is, I have ended up with a few techniques and examples, but I am not sure how to utilize them and what to do even if I get the PCA results. So, here I am looking for a code example through which I can implement PCA Analysis in Python on this sort of dataset as well as to understand how to interpret the PCA results and how to plot them..finally, how to interpret the plots. Many Thanks. </p>
