The graph is unparsable for me. Typically, for what I think is trying to be shown, you would put the requests per second on the x axis, you would put the response times on the y axis, and the color coding be to assign them a label of the framework. I'd probably use a line chart too since, as we increase rps, we expect a change in response time.

What the graph reads:

If my framework is beego and I want to get 30k rps, I would need to limit my data to processing times in the 0ms bucket. I think? Or maybe gin will allow for 7.5k rps if my processing time is 500ms?

Like, I think I can get to similar information to what you are trying to show if I read backwards, upside down, and rotated 90 degrees.
