Imagine two bar charts with x-axis of 1,2,3,4. The first has 2,4,2,4 as the height for each container ( ie there are 2 1s, 4 2s etc). The second has has 6,12,6,12. I want a percentage from 0 to 100% of how closely the first one matches the second (in essentially being a kind of subset). In this example, it would be 100%. Say we had a third of 6,11,6,12. I would want that percentage to be the ~80% or 90%s wherever it may lie. Is this possible?
