how to display the vertical section along latitude after usingsamplexy ?

Hi Ferreters,

I have used the function of Samplexy to  Subsample gridded fields onto profile coordinates as follow

yes? let my_lon = lon1[d=my_grid.dat]
yes? let my_lat = lat1[d=my_grid.dat]

yes? LET x_var = samplexy(temp ,my_lon,my_lat)

and I can display the vertical section well along the axis's number.

When I try to use latitude as x-axis as follow

let order = SORTI(my_lat)

let section = SAMPLEI(x_var, order)

DEFINE AXIS/Y/NAME=yax_sect/FROM_DATA/UNITS=degrees SAMPLEI(my_lat, order)

LET ysection = RESHAPE(section,Y[gy=yax_sect]+Z)

contour ysection
 **ERROR: unknown defining grid: GY=YAX_SECT --> g=user-or-pseudo-var not allowed
That is the problem.
