I just played around a little with Custom Events. My goal was to send performance data, such as average FPS values and I wanted to visualize them on a graph. But the data explorer is only showing the quantity of received events, not the values themselves. I was expecting a bit more. The only thing I can imagine is setting up a Funnel and categorize FPS values, but that would only tell me if someone had a "Good" FPS rate or not. Say you want to know how long people need for one particular level, is it possible to visualize that?
