Comment (by karsten):

 dcf: Thanks for digging out the duplicates.  The issue is around for too
 long now, we should really fix it now (and close the remaining duplicate).

 Regarding your longer-term idea, I totally agree that Atlas could be
 smarter there.  But I also think that Onionoo could be smarter by
 providing data for `1_month`, `3_months`, and `1_year` in a single data
 structure by using a smarter format.  For example, rather than using a
 fixed-width data interval it could include a list of x coordinates for
 data points.  That would allow providing more detail for more recent
 dates.  And it would allow condensing long series of `null` y values into
 a single `null` value and kicking out the rest.  There are surely plenty
 of ways to be smarter here.  Part of me thinks we must be reinventing a
 wheel here, but that part is also too lazy to read up what wheels already
 exist.  Anyway, I think we should first build the short-term solution by
 just removing the graphs that don't have any data.  The other thing
 deserves its own ticket. :)
