Referring to the method I proposed for Problem with ParametricPlot Mathematica 10.0.2 throws an enigmatic error message:

Plot[Sinc[x], {x, 0, 5}, Method -> {MaxBend -> 1}]

MaxBend::deprec: MaxBend->1 is deprecated and will not be supported in future versions of the Wolfram Language. Use Method->{MaxBend->1} instead.

I don't know if this message is entirely a mistake or if it is really trying to tell me that there is a different form I should be using now. Is this same message generated by 10.1.0? Is there a known different form for MaxBend?

    $\begingroup$ I see it in 10.1 on Win8.1. $\endgroup$ – dr.blochwave Apr 15 '15 at 16:45

    $\begingroup$ Does the alternative Method -> {Refinement -> {ControlValue -> (* radian angle *) }} still work, tho? $\endgroup$ – J. M.'s technical difficulties May 13 '15 at 0:08

    $\begingroup$ Personally, I've always assumed it's a typo, that MaxBend is in fact deprecated, and the message was supposed to point the user to Method -> {Refinement -> {ControlValue -> (*radian angle*) }}. I was hoping someone from WRI would comment on your question, though, to clarify. Have you reported it to WRI? $\endgroup$ – Michael E2 Jul 5 '15 at 18:45

    $\begingroup$ It still works without any message for ContourPlot as used in this answer. $\endgroup$ – Karsten 7. Jul 5 '15 at 19:00

Earlier invalid assertion redacted.

Some spelunking reveals that the innermost (accessible) plot function called is:

Visualization`Core`Plot

And using this function directly also produces the message:

Visualization`Core`Plot[Sinc[x], {x, 0, 10}, Method -> {"MaxBend" -> 1}]

MaxBend::deprec: MaxBend->7 is deprecated and will not be supported in future versions of the Wolfram Language. Use Method->{MaxBend->7} instead.

I have failed in my attempts to trace the origin of the problem further but I may try again later.

    $\begingroup$ Note that tr2 = With[{gr = 1/GoldenRatio}, Trace[{AspectRatio -> gr, Axes -> True, AxesOrigin -> {0, 0}, Method -> {"MaxBend" -> 1}, PlotRange -> {{0, 10}, {-0.21723357397428536, 0.999999999999993}}, PlotRangeClipping -> True, PlotRangePadding -> {Scaled[0.02], Scaled[0.02]}}]]; tr2 === Query[35, 1][tr] returns True. How do you deduce that "MaxBend" is being duplicated? It seems to me that the multiple instances could be the result of the evaluation chain. I note that some things are not evaluated to very bottom of the expression tree, so I might be wrong. Definitely confused. $\endgroup$ – Michael E2 Jul 10 '15 at 0:29
  • $\begingroup$ @MichaelE2 Facepalm -- no, I think you're quite right and I'm crazy. Trying too hard! $\endgroup$ – Mr.Wizard Jul 10 '15 at 0:31
