Big Number Chart in Percentage Form

What is the problem or goal the end user is trying to solve or accomplish?

We'd like the ability to build charts similar to the Big Number type but in a quick-glance percentage format.

How are they solving it currently?

We are currently without a good substitute, but have used side-by-side bar charts to show the visual ratio difference since there is no percentage-style big number chart.

What is the recommended solution by the Customer?

Allow the ability to convert the "Big Number" chart style into a big number percentage, comparing the data of interest as a ratio / percentage.
