Hi All,

I got a problem. The function ‘Tooptip’ doesn’t work properly with the function ‘InterpolationOrder’ 2 or 3, etc. but works fine with 'InterpolationOrder 0 or 1. Why???

dataMean = {32.4, 32.6, 39.3, 40.1, 45.2, 48.2, 48.8, 51.4, 52.5, 
   52.9};
dataMedian = {25.0, 27.0, 37.5, 38.0, 45.0, 52.0, 54.0, 59.0, 63.0, 
   59.0};
dataStDev = {25.1, 23.3, 26.2, 27.6, 26.8, 27.5, 28.3, 26.5, 27.5, 
   25.9};
ListLinePlot[Tooltip [{dataMean, dataMedian, dataStDev}]
 , InterpolationOrder -> 1 (* Always an ERROR message with 2 or 3, etc. *)
 , PlotMarkers -> Automatic
 , PlotRange -> {{1, 10}, {10, 70}}]

Please can you help ?

Thanks,…Jos

In the Tooltip documentations it says “Tooltip[expr] is equivalent to Tooltip[expr,expr].” but somehow this is not always the case because this works perfectly:

dataMean = {32.4, 32.6, 39.3, 40.1, 45.2, 48.2, 48.8, 51.4, 52.5, 52.9};
dataMedian = {25.0, 27.0, 37.5, 38.0, 45.0, 52.0, 54.0, 59.0, 63.0, 59.0};
dataStDev = {25.1, 23.3, 26.2, 27.6, 26.8, 27.5, 28.3, 26.5, 27.5, 25.9};
ListLinePlot[
 Tooltip[{dataMean, dataMedian, dataStDev}, 
         {dataMean, dataMedian, dataStDev}], 
 InterpolationOrder -> 3 (*Always an ERROR message with 2 or 3,etc.*),
  PlotMarkers -> Automatic, PlotRange -> {{1, 10}, {10, 70}}]

Hi Gustavo,

Thanks for your quick reply and help. I still got problems.

When I moved the cursor now over the PlotMarkers, the whole range of data is highlighted. See screenshot

Do you now why ??.

It looks like a bug. Anyway, this is longer but it works:

Show[
 Plot[
   Evaluate@Map[Interpolation[#, InterpolationOrder -> 3][x] &, {dataMean, dataMedian, dataStDev}],
   {x, 1, Length[dataMean]}, PlotRange -> {{1, 10}, {10, 70}}],
 ListPlot[Tooltip[{dataMean, dataMedian, dataStDev}], PlotMarkers -> Automatic]]

Hi Gustavo,

The problem is now solved and interpolation works perfectly. Thank you very much.

Yes, it’s probably a bug.

Best Regards and again thanks for your support. … Jos
