[ncl-talk] error in plot from data set of different number of grid points

[tms_l]

Dear ncl users

I would like to plot u & v components of wind along with mean sea level
pressure data.The wind data (time,level,lat_1,lon_1) is 4 dimensional and
mean sea level pressure data (time,lat,lon) 3 dimensional.

Also the number of grids points are arranged differently in each data sets.

For wind data latitude ,                        lat_1 = 144 points
                     longitude ,                     lon_1 =192 points

For mean sea level pressure latitude ,        lat =145
                                          longitude,       lon =192

I am getting the error message as follows and the mean sea level pressure
data seems to plotted reversely..Is there any function to deal with data
sets of different grid points or how can solve this issue? Any help will be
appreciated.
