Hi, i'm trying to implement this mertic. I calculate the ratio in two ways，the first is ratio = pr closed without being merged/pr merged, the second is ratio = pr merged/pr closed(including pr closed without being merged and pr merged)。The result is shown below

But i think the result not represented the ratio of change requests merged (accepted) vs change requests closed without being merged well. Maybe I should use a histogram，just like the Instance of Implementation？Can anyone give me some advice？ @xgdyp

I agree that the histogram is a better presentation here.

As for the value itself, I think the second way (merged/all closed) represents the meaning of this metric as "the ratio of accepted PRs among all the PRs"
