Hi Xiaoming,
<div>You data does have some discontinuities (between time steps 17 and 18, also between 36 and 37) which is why NCL is having trouble generating a continuous time axis. However, in this case, If you follow the suggestion given by the warning message, you can
get it to work. I set trXTensionF to 9.0 and I got a valid plot. You might also want to set gsnXIrregularToLinear to True depending on what your goal is. If you data had bigger holes</div>
<div>you probably could not use trXTensionF. In that case you might need to generate some reasonably spaced intermediate pseudo coordinates values with fill values for the data values. </div>
