Smoothen the contours with InterpolationOrder in ListContourPlot?

Questions
1

Hi,

In the ListContourPlot example below, I am trying to smoothen the contours by using the function InterpolationOrder with different numerical values, but it is not making any impact on the roughness of the contours.

Will appreciate any help. Thanks

XX = {{0., 0., 14}, {0., 0., 2}, {0.149508, 0.076178, 7}, {0.153488, 
    0.0498713, 7}, {0.156435, 0., 4}, {0.302952, 0.0984348, 
    7}, {0.309017, 0., 4}, {0.444473, 0.144418, 7}, {0.451668, 
    0.0715374, 7}, {0.453991, 0., 4}, {0.574342, 0.186615, 
    8}, {0.584501, 0.0925761, 7}, {0.587786, 0., 4}, {0.689152, 
    0.223919, 8}, {0.702713, 0.111299, 7}, {0.707107, 0., 4}};
ListContourPlot[XX, ColorFunction -> "TemperatureMap", 
 PlotLegends -> 
  Placed[BarLegend[{17, 34, 51, 67}, 
    LegendMargins -> {{0, 0}, {10, 5}}, LegendLabel -> "% output", 
    LegendMarkerSize -> 150, 
    LabelStyle -> {Italic, Bold, FontSize -> 15, 
      FontFamily -> "Helvetica"}], {{0.1, 0.5}, {0.1, 0.1}}], 
 Frame -> False, BoundaryStyle -> {Black, Thick}, 
 InterpolationOrder -> 3]

  • There is an issue with you data: {{0., 0., 14}, {0., 0., 2}, … is a contradiction.
  • Apart from this - if you try an interpolation, you get the message:

The same seems to hold for ListContourPlot.

Thanks for your response and pointing out the error in data set ! Even after removal of bad data point, I am not able to get any change in roughness by using Interpolation order 1.

Attached picture has my real data and I want to remove this wavy boundary between two regions. How can I do it. Any option other than Interpolationorder function ?
Cheers.
