Which curve represents the spontaneous reaction, and which the nonspontaneous?

I found a similar question that I've found online which provided a graph. A spontaneous reaction is characterized as having a negative value of the change in Gibb's free energy. Thus, the free energy at the end of the reaction must be less than that at the start, to make it negative. With that being said, the red curve represents the spontaneous reaction, while the blue curve is for the non-spontaneous reaction.
