Hi all, I am contouring (contourf) a time series of signal to noise ratios. contourf(timeseries, heightsAboveGround, signal2noise). I am getting different results now than I did with the pevious version of matlab. In the old matlab (last version) I could contour a time series with no problem and the dates would appear at the bottom of the image. Now when I do I get strange trelaunay like shapes, albeit then the dates still appear. Of course, if I contour the data only, then I can get a proper contour plot, but that means I would have to put the dates in manually. In the last version of matlab this was not necessary. It's rather annoying. Can anyone explain or offer a solution? I'll attach pictures. Thank you so much. Mark J. Dempsey

Hi there, forgive the delay in my response, I didn't realize someone had responded to me and now I feel like an oaf!
Yes,
The code is the same for each version.
contourf(TIME, LEVELS, SNR); datetick;
I have attached the data to this response.
Thanks so much. mark
