Sparklines displayed over multiple cells (not in one cell)

Hey reddit,

I have a lot of numbers on one sheet and I have thought of using the sparklines to visualise them. However, the problem with the standard sparklines is that they are normally located in one cell, which is, when you have 15 years to compare, not quite handy.

Is there a way to place this sparkline (or vertical bars, it does not matter) across these 15 years, so that for each number its relation to the neighbouring numbers is visible? Here is what I mean:

The red line is the sparkline over multiple cells that I am looking for

Creating a mini-graph for each row is not an option due to amount of numbers.

Thanks in advance for any suggestions!

Best,

Andrei
