Very nicely presented. I presume the plan is to have one of these per month per console?
For visual aesthetics, and possibly for ease of reading it, I think the main "total sales" graph would be better with a taller ratio. Like 50% if not 100% taller... if you are trying to make the whole "profile" fit into a space maybe just move the graph key to the side.
Also you say 84th month but if launch month November is month 1 (or technically month 11 as you are aligning months), then the most recent November should be 85 afaik... your graph also goes up to month 86, but I presume that is because you have to have some data in for December (even though it's incomplete) due to the month aligned nature?
And not sure I fully understand the "trend" column in your gaps table... specifically what's a "retraction", and in general what is it comparing with what?
If i'm reading it correctly the top 9 consoles are the difference in LTD sales to the PS4s 84th (85th?) month, so it's 34mil behind DS but ahead of everything else at the equivalent point in it's life... then the final 3 consoles will just be comparing The LTD at their most recent November, to the equivalent PS4 November (probably need to separate them more visually somehow , maybe put in something to note which year is being compared)
Actually come to think of it, how does the gaps table deal with staggered launches... the 4th November for Switch was it's 45th month on the market, but the 4th November for PS4 was only it's 37th month, comparing the equivalent months is fine but when bringing LTD totals into the equation I presume you are adding in the other months of the 4th year for PS4?
So the comparison is: (Switch LTD to Nov2020) VS. (PS4 LTD to Nov2016 + PS4 Mar-Oct2017) ???
Please let me know if I got that correct, if so then it's just the "trend" column I still need explaining.
