Without being able to run your script, I can't tell you exactly why this error is occurring, but my guess is because your Y axis coordinates are irregularly spaced, and hence that turns your whole plot into an "irregular" plot. This means you can't arbitrarily set the min/max values to something outside the range of the data.</font></span></p></div><div class="gmail_default"><font face="arial, helvetica, sans-serif">The second is that you are adding lat2d and lon2d attributes to your data variables, but this doesn't make any sense because your data is not over a map.
