so does anybody know how a video with a misaligned log scale even looks? like what does a log scale even mean for a video? 172.71.99.18 19:30, 22 January 2024 (UTC)mstrofcmdy209

I think he's suggesting that the video shows the changes in a graph over time, and the misalignment could also change during the video. Barmar (talk) 20:47, 22 January 2024 (UTC)
Imagine that a plot is just a 2D picture, or even more fundamentally as a function taking two variables and returning a pixel color. Changing an axis of the plot to be logarithmic is equivalent to applying a non-uniform scaling to one of the input variables to that function. In this comic that non-uniform scaling has instead been applied along an axis that does not correspond to either the X or Y axes but instead some combination of the two. A video can similarly be thought of as a function of 3 variables (X, Y, T) and so the non-uniform log scaling could be applied along an axis that is some combination of the X, T, and T axes. 172.71.154.252 23:37, 22 January 2024 (UTC)

Shall we try to straighten out the plot with regards to the axes, leaving the log stripes all wavy? For kicks? -- Enfield (talk) 02:14, 23 January 2024 (please sign your comments with ~~~~)

I feel like this comic, along with others like 2023: Y-Axis and 2311: Confidence Interval should go in a category for misleading charts. -- 172.69.33.111 (talk) 02:23, 23 January 2024 (please sign your comments with ~~~~)

It may be interesting to refer to a tephigram instead of, or as well as, a SkewT-LogP as a tephigram has no normal axis. In my opinion, this makes the point even stronger. A tephigram shows the same lines as a SkewT-LogP but pressure is drawn as a curve, which straightens out the entropy lines. Temperature (te) and entropy (phi) lines are straight and normal to each other, but at around 45° to the page. 172.71.178.176 14:14, 23 January 2024 (UTC)
