Question about grey bar on statics dashboard

Hello,

What does the grey bar on the statistics dashboard mean?

I cannot seem to make sense of it.

Thanks!

orschiro I believe it's the previous 7 days.

clarkwinkelmann thanks but I thought that's the green line?

Grey Line is previous period. Green Line is last period. Depending on selection.

luceos thanks! So for example, green line would be last 7 days and grey line the 7 days before that?
