title: How to transform oscillating data
body: <p>I have data that looks like the following image, but reversed, starting small and increasing over time. All of the data is currently in a csv file, with time being one column and the values being another. I was wondering what transformations would be possible in order to use the data and discover trends or a relationship. Thank you!                                                                      <a href="https://i.stack.imgur.com/TrPC7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TrPC7.png" alt="enter image description here" /></a></p>
