[gradsusr] wrf output data in lambert projection plot problem

[Fu Kai]

 Dear GrADS Users,

I am beginner to wrf and GrADS, and want to display the output data of wrf
using GrADS, I used the wrf2grads program to get the ctl and dat file which
are needed by GrADS. When I tried to plot the data, there seems to be a
problem, the figure does not coincide with the lat and lon lines (Fig 1). I
thought it was because the case uses a lambert projection, while the default
projection used by GrADS seems to be Mercator, so I tried to use "set mproj
lambert" in GrADS, but only get a small figure (Fig 2) which also seems not
properly. Which command should I use to get a right figure.

Any suggestion would be greatly appreciated.  The CTL file and the figure
plotted are below.  I'm a new GrADS user, so if this is a newbie problem, I
apologize in advance.

CTL file created by wrf2grads program:
