 Travis failures is from `TestTSPlot` and isn't related to this change Looks good! @toobaz do we merge this one first, and then you update your PR? Yes, I will rebase, no problem. Just made a small change to "Like" -> "Equivalent" (I *think* you cannot use "like" as an adjective like that? but may be wrong) @WillAyd Thanks for the updates!
