Unexpected behavior of modx.values when values are not repeated

Maybe you will want to fix it. `interact_plot()` has a strange behavior when modx.values has a value twice like c(1,1,0,-1). It seems like it treat it as a supplementary moderator. See picture for details.

Thank you for your work and have nice day. Cordialy,


Start with the interact_plot() entry point and reproduce the behavior using modx.values = c(1, 1, 0, -1). Compare the resulting plot with the attached example; done means repeated values are handled as intended rather than treated as a supplementary moderator.
