Feature Request: Compare Data to Previous Range in Charts

It would be GREAT if we could easily compare the current data to the previous range. For example, when I’m looking at this year’s revenue chart, I want to see how that compares to last year’s revenue. Or if I’m looking at the last 28 days of new subscriptions, I want to know how does that compare to the previous 28 days? This is pretty easily done with line charts, by adding another line with less opacity or a different color, but I understand it might not as easy to implement with other chart types or segmented charts.
