Yes, I'm using the community server. So I took a look at one of the examples experiments and I am able to individually change the color of different lines e.g the "scalar reporting" example. I wonder if it has to do with how I called the reporting function for my experiment?
HighOtter69 inside the legend click on the color rectangle next to the series name, you can change the color of the series on the graph. This property is stored so it will always remember your color preferences (yes even logging from another machine 🙂 )
I think there is a bug on the UI that causes series with "." to only use the first part of the series name for the color selection. This means "epsilon 0" and "epsilon 0.1" will always get the same color, and this will explain why it works on other graphs
