Take the reference that is 5min ago, call it T0.
You will still observe that temperatures (i.e the sequence of measured temperatures minus T0) are increasing.
Changing the reference changes the y-scale of a graph, but does not change the derivative (the speed at which it changes, i.e. increases or decreases).
- joatmon-snoo 10y agoDid you look at the graph? The local derivative is most definitely not indicative of a general trend. For comparison, I throw a ball down at the ground, and for the first 0.1 seconds it's moving down - can I conclude that the ball is going to keep moving down, even when it hits the ground? That's your logic.
- stale2002 10y agoI don't think you know what baseline means. Baseline is just the starting point of the x-axis. It doesn't matter. Personally I'd set the baseline to 0 degrees. Because thats how temperature works. But you can pick whatever you want. It does not matter what you x-axis starts at. It doesn't change the data. Or you could just have no baseline. Just remove the X-axis line from the graph.
- sanderjd 10y agoWhat? Just because it's daytime (in the US) right now? In a few hours when it's dark, the temperature will definitely be going down when compared with a baseline of 5 minutes in the past. I don't think you've thought this through...
