I saw a forum that was similar to what I asked, but not quite. Though feel free to redirect me.

Recently, I've gotten my friends into a game I've been speedrunning. I want to be able to have our data displayed with a graph so I can see how everyones times are improving amongst each other over history. I came pretty close to doing this with a line graph, but the lines were sloped instead of static, and also the data wasn't showing in mm:ss format.
