# Talk:2864: Compact Graphs

Suggestion for X-axis: red - yellow - green - blue (like visible light spectral colours, but in reverse direction)

Suggestion for y-axis: 62 (red) - 159 (yellow) - 187 (blue) - 205 (green) - 230 (blue)

If the second "graph" really is a representation of the same data as the first, there should be *five* points, corresponding to (approximately) {(17, 62), (36, 159), (67, 206), (88, 186), (100, 232)}. I copied the first plot to GIMP, cropped it, scaled it to 100x250, and measured the centres of the dots. :-) BunsenH (talk) 02:19, 7 December 2023 (UTC)

I agree with five labels. Combining these information above so far, and adding information from the Color Model HSV (also extracted with GIMP, from the large file :-)

17, **62**, hue 13 (red, HEX ff3a00)

36, **159**, hue 51 (yellow, HEX ffdb0f)

67, **205**, hue 87 (green, HEX 8afc03)

88, **187**, hue 169 (turquoise, HEX 08a387)

100, **230**, hue 217 (blue, HEX 0060ff)

Does anyone find a consistent/proportional correlation between x-axis and HSV-hue? If not, it makes not much sense to mention the x-axis values in the explanation.

- Sorta! It lines up with the x values for 3 of them and the y values for 2 of them, which is unlikely to be a pure coincidence. Attempted to explain all this in my edits just now. Laser813 (talk) 20:32, 7 December 2023 (UTC)

Should we link to 2537: Painbow Award Kvarts314 (talk) 10:43, 7 December 2023 (UTC)

I think we're still missing the joke. In graph theory, there's a number of important problems and theorems related to colouring and to compact graphs (although I don't think many problems involve both concepts). Someone better versed in graph theory should chime in. 172.69.214.109 15:27, 7 December 2023 (UTC)

- I personally don't think it goes that deep, but I'm not a graph theory expert. Laser813 (talk) 20:32, 7 December 2023 (UTC)

Perhaps someone better at graphics than me could create a "key" for the Hue-Label graph, showing how the colors from 0 to 360 hue correspond to numbers? Laser813 (talk) 20:32, 7 December 2023 (UTC)
