time labels error

HI,

I am trying to plot using the time_labels_3.ncl script at http://www.ncl.ucar.edu/Applications/time_labels.shtml. The error message I got is:

¡°
warning:Invalid stride: stride must be positive non-zero integer
fatal:CheckArray:Each vector in the caXArray array must have at least 2 elements
fatal:CoordArraysInitialize:caXArray resource is invalid
fatal:Unable to initialize layer-Can't Create
fatal:Unable to access object with id:-4
fatal:Unable to access object with id:-4
warning:Unable to add DataItem "(null)" to DataList "xyCoordData"
fatal:CompileDataList:DataList has no valid members
fatal:Unable to access object with id:-4
warning:Unable to add DataItem "(null)" to DataList "xyCoordData"
fatal:CompileDataList:DataList has no valid members¡±

I just changed the wrf output fiile to my own one.
