Hello u/Mental-Ad-40. Good example, the one you put in a comment in this discussion (very very much below, for this reason i put this comment here, above). You remember us that "line graphs" are used not only with "time" in the "x axis", with this good example:

I'm the author of this published graph of metal bands. Certainly i had never heard about this association with "line graph" and "time". But i recognize that i'm a perfect newbie doing statistical graphs, so i consider a good learning for me all the good comments here 😅

Said this, i appreciate your line chart with temperature-pression, because certainly it's a good counter-argument on that supposed strong link between "line graphs" and "time X axis".

My unique concern now is how to represent in the future this kind of data without using LINES. I don't like to put 2 bars for each country, because it usually connotes that both bars are corresponding to the same "metric" or same "nature". For example:

bar 1: number of metal bands
bar 2: number of pop bands

But in my case bot metrics are of very **different nature**: they are **not comparable**. One es number of things, and the other is number of things per capita ! Do you understand me?

Someone has any good answer for this kind of data to be rendered in the same graph?

I was very interested in your chart because it gave me a chance to think about how I would present it based on some of the feedback you got. Here is my version presented according to the three parameters.

Edit: when I looked up the data I came up with slightly different numbers than you.

Wooowww, all 3 are wonderful!! 🤩

Maybe the first or the second one are the best for me. But you really were able to include 3 metrics in the same graph... i love it.

I realize now that it would be a good idea to also share my exact NUMBERS used to build a graph. In this case you had saved time getting the values for each country 😅

Thanks master! Which software did you used?

Thanks for your compliments, but I am a beginner at making graphs and I learned a lot from making this. I used Excel. I was just lucky that the right side axis label works for both the population in millions and the number of bands.

to be honest, I think the difficulty of correctly representing this data comes from trying to plot two conflicting perspectives on the same graph. I think you should have just included either or. Like you could put bands per million in bars, then just country population if you wanted to include demographics too. Or if the absolute number of bands was the important bit, include just that. If you really want to show both, use two separate graphs to allow the reader to see the perspectives separately, the same way they should think about them.

But if you must include both of these data points exactly as is and in a single graph, you should probably use a scatter plot.
