TwitchTracker is one of those stat sites derived from Twitch where you can see charts of what has been going on about a particular stream over a day period or the entire streamer life period. Here is one example with average viewers and hours streamed, spanning over the streamer life period :


Chart from TwitchTracker : there is something hard to understand

There is something hard to understand, which is the fact that it's impossible to tell to which axis the series of data belongs to, i.e. average viewers are on the left scale or on the right scale ?

Since scales on the left and on the right are different, an easy fix to the problem one would assume is to make those scales equal.


Chart from TwitchTracker : equal scales does not really improve the situation

But this does not improve the situation since we have had to change the scale which means either stretch the graph or downsize it. We may lose visual significance doing so.

So the solution is quite simple. Just color the axis labels with the same color than graphs.
