The InterpolationOrder option just does that
InterpolationOrder
try the following
Manipulate[ ListContourPlot[ Table[Sin[i + j^2], {i, 0, 3, 0.25}, {j, 0, 3, 0.25}], InterpolationOrder -> ord], {ord, 0, 5, 1}]
your command , It is very useful! thank you
Regards
Go to the help page for ListContourPlot
Click on the Details and Options
Scroll down to see that it accepts an InterpolationOrder option to let you specify the order
I have tried, It runs. thank you a lot
