Some time ago I noticed that the rating line chart uses smoothed line.
I am personally against thist choice because I think it’s less accurate.
Look at these data:
If we use a straight line it looks like this:
The smoothed line adds information about trend that isn’t in the data.
In order to round the corners it goes above and under the actual values in the series.
I’d also say that each individual game is a distinct event, not actually a step in an overall path.
I think it would make more sense to represent games as points. The user’s games history is actually a point cloud, where many things happened: undeserved wins, stupid loss, timeouts and so on. The overall behaviour is not in the interpolation of every single event but in the global trend line.
I know this introduces a new argument: which trend line to choose?
This could be a problem. But, trying to keep it simple, I plotted this: it’s a 2d degree polynomial trend line on my personal data.
I think it actually makes more sense than the straight plotting of rating changes:
I fear I’ve gone far away from the initial argument.
So, back to topic: could you please discard the smoothed line and revert back to the straight one?
