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}};
