error message

I don't seem to be able to find this topic in your archive but I got an error message from an NCL script:

fatal:_NhlGetEndpointsAndStepSize: Max value less than or equal to min value

I was plotting a time series and the data were constant with missing values. How to avoid or fix the error?

Thanks.
