Hi, I have a problem with contour lines appearing completely straight. The data has been exported as a netcdf file from another app, and imported using visad.data.netcdf.InputNetcdf. I have to muck around with the data somewhat as the data out of the netcdf file is a bit different to what I want; it's ((Latitude_Longitude_ndx -> (Latitude, Longitude)), (Time -> (Latitude_Longitude_ndx -> anal0))) where I want (Time -> ((Latitude, Longitude) -> anal0)) but I'm fairly sure that this part is correct. When the data is added to the display with a ScalarMap to IsoContour, I see straight lines that zigzag their way through the data points. If I also add a map to RGB, the lines become horizontal only (ie the "zags" disappear) and are now coloured. I expect to see curved contour lines, but don't. Is this familiar to anyone, and is there something obvious that's wrong? I can supply the shortest program and netcdf file to reproduce the symptoms if required.
