How to deal with 2 TimeSerieses with the exact values?

问题

I'm creating a TimeSeries chart with 2 TimeSerieses in it (i.e. A Dataset holding 2 TimeSeries objects.

It happens that both TimeSeries objects holds the same exact values and they are simply overlapping but that's not clear to the client as he only sees the result color or mixing the colors of both TimeSeries objects !

So he's seeing that the chart is displaying 2 sets of data, while only one line is drawn !

Is their a build-in way to deal with that ? How would you fix that ?

Personally I'm thinking of splitting this chart into 2 for it to be clear to the customer but I'm wondering if there is a way with less effort\more efficient to solve this situation.

EDIT: Final output should be images so this isn't a desktop application (i.e. Swing)

Thank you.

One approach is to let the user control series visibility using a suitable Action, a shown in this example.
